- Measure the dial and backing thickness; distinguish total shaft length from the threaded section in the exact seller diagram.
- Record the original hand mounts and compare them with the specified replacement hands; do not assume matching appearance means matching fit.
- Check case, dial, hand and glass clearance before ordering. No universal short-shaft size or adapter is established here.
Quick picks
Three seller-listed kits: compare dimensions and hand mounts
Key checks
Fit checks before ordering a replacement
Record the dial and backing thickness. Compare it with the exact variant’s threaded section, total shaft and mounting arrangement; those dimensions describe different parts of the assembly.
Identify the hour and minute hand mounts separately. Confirm compatibility with the exact replacement movement; the included hands do not prove that the original hands fit.
Record hand dimensions and ask the supplier which hands the exact movement supports. No tested load rating for original mechanical hands is established by this comparison.
Compare the movement body, mounting hardware and available case space. Confirm clearance from the dial, other hands and glass using the exact instructions.
Shaft measurements
Keep panel thickness, total shaft and threaded length separate
Measure shaft length and profile
Use the replacement supplier’s diagram to identify each dimension. Clockparts’ repair selection page requests overall and threaded shaft measurements, dial or mounting-material thickness, minute-hand length measured from hole to tip, and glass clearance. Its own replacement route warns that original hands cannot be reused with its motor. That is a supplier-specific warning, not a fit result for the three marketplace kits below.
Tools
- A measuring tool suitable for the exact supplier’s drawing; display resolution alone does not establish measurement accuracy
- Thin depth gauge or ruler
- Small straightedge and marker (optional)
Step‑by‑step measurement
- Photograph the installed assembly and identify the movement before dismantling it. Use the exact removal instructions or ask a clock repairer if the original hands or dial may be damaged.
- Record the dial and any backing or mounting-material thickness. Keep that measurement separate from shaft dimensions.
- Record total shaft length and threaded length using the reference points in the exact movement drawing. Do not compare differently defined dimensions as if they were the same.
- Photograph the original hour and minute hand mounts and record the replacement’s specified mounting pattern. Ask the supplier to resolve any unclear dimensions before ordering.
Interpreting labels and tolerances
- Short, medium and long labels are not universal dimensions. For the Toughwild kit below, the seller lists 16/20/23 mm total shafts and separate panel ranges of 0–4, 4–8 and 8–12 mm. The panel ranges are not shaft lengths or proof of original-hand compatibility.
- Check clearance between the hands, dial and glass using the exact movement-and-hand instructions. No universal gap or dimensional tolerance is established here.
If a shaft dimension or mount is unclear, send the supplier photographs and measurements rather than forcing a trial fit. Clockworks’ quartz selection guidance distinguishes the threaded post from the hand-mounting portion for the movements it sells; its chart is not a compatibility chart for unrelated kits.
Conservation guide
Compatibility and repair limits before alteration
Preserving or retiring original hands
Original mechanical hands are not a confirmed match for these quartz kits. Record their condition and mounting pattern before considering a conversion. If preserving them is important, ask a clock repairer to assess the original assembly and proposed replacement. The related keeping original hands when converting page is additional reading, not confirmation that a particular kit will fit.
No bushing, collet, glue or hub-modification procedure is established for these three kits and an unidentified original hand. Do not press, glue, ream, file or trim parts to make an unconfirmed fit. Ask for a specified compatible hand-and-movement combination or obtain a repairer’s assessment before changing original parts.
Document cracks, corrosion, missing material or previous alterations before seeking advice. Do not install a damaged hand or reshape it to clear a new assembly without a model-specific repair assessment. A styled replacement may be an option, but its mounting pattern and dimensions still need to match the selected movement.
Document the original hour and minute mounts and any visible damage.
Compare them with the exact replacement specification.
Do not assume a bushing, collet or adhesive will provide a suitable conversion.
Ask a clock repairer before removing or modifying parts you want to preserve.

Hand mounts and compatibility questions
Rapid profile mapping
Describe the shaft and hand holes to the supplier; their appearance alone does not identify a suitable adapter. Clockworks’ design-hand page describes an oblong minute-hand hole and round hour-hand hole for its I-shaft hands and scopes compatibility to movements it sells. That does not establish a match for original mechanical hands or every kit with an I-shaft label.
- Tapered or conical mount: photograph the profile and ask which exact hand-and-movement combination is specified. No tapered sleeve or collet is prescribed here.
- Straight round mount: record the dimensions and mounting instructions. A round hole alone does not establish a compatible bushing or press fit.
- Splines, keys or flats: document their shape and ask for an exact compatibility check. A generic conversion collet is not a confirmed solution.
- Worn or oval hole: document the damage and ask a repairer to assess it. Reaming or fitting a new bushing is not a general conversion step.
Observations to discuss with the supplier or repairer
Photograph visible conditions without forcing a hand onto or off an unidentified mount:
- Record any existing wobble or loose fit. Those observations alone do not establish the cause or the correct repair.
- Photograph cracking, corrosion or thin material around the hole. Do not infer that a bushing is the appropriate repair.
- Ask how the specified compatible parts will clear the dial, other hands and glass. Do not select an adapter solely to change hand height.
For broader notes on fitting choices and movement options, consult the hand mounting compatibility guidance.
TIKROUND gold-hand listing
Check the listed shaft and panel dimensions
01 Seller-listed 18 mm total shaft / 5 mm thread
The B08SQFD259 seller listing names an I-shaft movement with an 18 mm total shaft, 5 mm threaded section and a panel range of 1–3 mm. It lists a metal hook, replacement hour and minute hands, mounting hardware and instructions. These are listing details, not a measured fit result for your dial or original mechanical hands. Check the exact variant drawing and supplied hand mounts before ordering.
- Seller lists an 18 mm total shaft and 5 mm threaded section
- Seller states a 1–3 mm panel range
- Replacement hour and minute hands are listed
- Hook and mounting hardware are listed
- Seller identifies an I-shaft pattern; verify the exact drawing
- Original mechanical-hand compatibility is not established
- The seller’s 1–3 mm panel range is not a universal small-dial rule
- Torque, noise and long-term reliability were not tested here
- No short-shaft adapter or hub-trimming method is verified
Consider this listing only after its shaft diagram, stated panel range and hand mounts have been checked against the intended assembly. The listed replacement hands do not establish that original mechanical hands can be retained. No comparative fit, torque, sound or durability test was performed for this guide.
Three-size kit listing
Compare each movement and its replacement hands
Seller-listed three-size kit with replacement hands
The Toughwild B0FGXXRMPN listing names three movements with 16, 20 and 23 mm total shafts, panel ranges of 0–4, 4–8 and 8–12 mm, and eight pairs of short replacement hands intended by the seller for 3–6 inch dials. The seller also claims quiet sweeping operation; this guide does not verify sound, accuracy or runtime. Confirm the selected movement’s drawing and hand mounts rather than treating panel ranges as shaft lengths or a promise to retain original hands.
- Seller lists eight pairs of short replacement hands
- Seller lists three total shaft lengths: 16/20/23 mm
- Seller separates panel ranges: 0–4, 4–8 and 8–12 mm
- Seller describes sweeping operation; sound is not verified here
- Three movements and replacement hands are listed in the pack
- Original-hand compatibility is not established
- Exact torque and supported original-hand load are not verified
- No comparative lifespan or durability evidence was obtained
- Confirm the supplied hand styles, dimensions and mounting pattern
Seller-listed 18 mm total shaft / 5 mm thread
The B074GQXPW1 listing identifies TIKROUND-M-031 and states an I-shaft movement with an 18 mm total shaft, 5 mm threaded section and a 1–3 mm panel range. It lists a metal hook, replacement hands and mounting hardware. The 12888 name, long-spindle wording and included hook do not establish higher torque, stronger construction or suitability for heavier original hands. Compare the exact drawing and compatible hands.
- Seller lists an I-shaft movement and names TIKROUND-M-031
- Seller states 18 mm total shaft and 5 mm thread
- Seller states a 1–3 mm panel range
- Replacement hands and mounting hardware are listed
- A metal hook is listed; it is not a comparative durability result
- Original mechanical hands are not a confirmed match
- Included replacement hands may differ from the original appearance
- No comparative body-size or strength assessment was performed
- No generic adapter, higher-torque or smoother-running claim is verified
Check the B074GQXPW1 variant against the actual dial, mounting arrangement and specified compatible hands. This guide does not establish that its torque, durability or fit is better than B08SQFD259, or that the 12888 label makes it suitable for heavier original hands.
Pre-installation checks
Checks before removing or installing parts
- 1. Identify the assembly
Photograph the movement, dial and original hand mounts. Obtain the exact removal and installation instructions before dismantling anything. Ask a repairer if the original parts may be damaged.
- 2. Compare the exact drawing
Record panel thickness, available case space, shaft dimensions and hand mounts. Ask the supplier to confirm the intended movement-and-hand combination; do not force a trial fit.
- 3. Confirm clearance requirements
Check the exact instructions for clearance from the dial, other hands and glass. No universal gap, shim thickness or spacer prescription is supplied here.
- 4. Follow the specified fitting method
Use the instructions for the exact compatible movement and hands. Do not assume every hand is pressed on, uses a collet or shares the original assembly’s fitting method.
- 5. Check operation as instructed
Use the supplier’s specified checks after assembly. Stop if there is rubbing, binding or irregular operation; do not bend, glue or modify parts to conceal an unconfirmed fit.
This checklist does not replace model-specific conversion or repair instructions. No successful conversion of original mechanical hands was tested for this guide.
Do not use a generic quick fix for an unconfirmed fit.
If hands rub, bend or slip, stop and compare the exact assembly with the supplier’s instructions. No shim, plier-straightening, collet-pressing or stronger-movement substitution is prescribed here.Clockparts.co.uk’s compatible-hand page warns that removing its tightly fitted metal seconds hand can pull out the spindle. This is a supplier-specific warning; it does not establish a removal method for other hands or the kits above. Ask before forcing a part.
Troubleshooting
Common questions — short answers
Hands scrape the dial after installation. Why?
Scraping alone does not establish the cause. Stop and compare the dial, hand mounts and clearances with the exact movement instructions. Do not assume a spacer, shorter shaft or reshaped hand is the correct remedy.
Will a short‑shaft kit damage original hands?
A short-shaft label does not establish compatibility or prevent damage. Confirm the exact hand mounts and removal/fitting instructions; no generic collet, bushing or adapter is verified for your original hands.
Is torque from small kits enough for metal hands?
This guide has not verified a load rating for original mechanical hands. Ask the supplier which hands the exact movement supports. Shaft length, price and the 12888 name do not establish torque.
Can these kits convert a mechanical clock to quartz?
No complete mechanical-to-quartz conversion is verified by these listings. The movement, dial, mounts, hands and case need to be assessed together. Consult a clock repairer before altering an original or heritage assembly.
How this comparison was prepared
This comparison uses saved seller listings and supplier-specific measurement and compatibility guidance. No bench fit, torque, sound, runtime, timed installation or original-hand conversion test was performed for this guide.
- Seller-listed dimensions
Compare the exact ASIN’s stated total shaft, thread and panel range. Listing labels are not independent measurements or universal standards.
- Hand-compatibility limits
Distinguish included replacement hands from original mechanical hands. Supplier guidance for its own movements is not proof that unrelated kits or adapters fit.
- Unverified outcomes
No comparative winner, load capacity, sound level, durability or conversion success is established. Obtain the exact instructions before changing original parts.
Before choosing
Compare the exact assembly, not the ranking labels
- Original mechanical hands are not a confirmed match; obtain the exact movement-and-hand specification before altering parts.
- Use seller dimensions as listing information, not proof of torque, quietness, durability or conversion success.
The two TIKROUND listings state 18 mm total shafts, 5 mm threads and a 1–3 mm panel range. Toughwild lists three total shaft sizes and separate panel ranges with short replacement hands. These differences provide details to check against an actual assembly; they do not establish an overall winner, a higher-torque option or a way to preserve original mechanical hands. Ask a clock repairer if the conversion requires unknown adapters, altered hands or casework.
