Top 10 Of The Best La Crosse Technology Atomic Clocks

La Crosse Technology WT-3129B 12 Inch Atomic Analog Wall Clock, Pack of 1, Black

9.9
$34.00
Amazon.com

Overview

La Crosse WT-3129B is a 12-inch black analog wall clock for indoor use. Its matte plastic frame has a silver bezel, while the movement receives WWVB time from Fort Collins and offers four United States time-zone positions with automatic DST adjustment.

Key Features

  • The round analog case measures 12 inches across and weighs a listed 1.7 pounds.
  • Time-zone choices are Pacific, Mountain, Central, and Eastern.
  • The technical attributes say one AA battery is required and batteries are not included.
La Crosse Technology WT 3129 B 12 Inch Atomic Analog Wall Clock, Pack of 1 , Black featured photo

Considerations

The product text conflicts on power: one passage claims three AA cells can provide up to five years, while another and the attributes specify one AA. Confirm the exact battery compartment and current manual before ordering. Also verify case depth, lens, rear hanger, manual-setting fallback, and reception at the planned wall; the five-year figure is a claim, not a guaranteed interval.

La Crosse Technology WT-3129S 12" Atomic Analog Wall Clock, Silver

$39.99
Walmart.com

Overview

WT-3129S is the 12-inch silver version of La Crosse's radio-controlled analog wall clock. It sets its hands from the Fort Collins signal, provides four time zones, and allows automatic Daylight Saving Time adjustment to be switched on or off.

Key Features

  • Normal operation begins with one AA alkaline battery in the main compartment.
  • Two optional AA cells can be added in a separate compartment to extend operating time.
  • A manual reset button is available when radio reception is unsuitable.
La Crosse Technology WT 3129 S 12 Atomic Analog Wall Clock, Silver photo

Considerations

The claimed extension is up to three years with the two extra cells, but battery inclusion is not stated. The description advises manual setting beyond roughly 2,000 miles from Fort Collins. Confirm supported zones, initial synchronization, case depth, lens material, hanger design, and actual compartment layout. No outdoor-use rating is provided, so keep this model indoors unless its manual says otherwise.

La Crosse Technology Atomic Analog WT-3102S-INT Wall Clock, 10 Inch, Silver

$28.97
Amazon.com

Overview

La Crosse WT-3102S-INT is a compact silver analog wall clock with a 10-inch case and roughly one-and-two-thirds-inch depth. A flat lens shields the dial, and the chrome-colored frame is edged with black inner trim.

Key Features

  • Atomic time includes manual setting and automatically sets to exact time.
  • Four United States time zones and switchable automatic DST adjustment are documented.
  • One AA battery is required, is purchased separately, and powers the atomic movement.
La Crosse Technology Atomic Analog WT 3102 S INT Wall Clock, 10 Inch, Silver featured photo

Considerations

This is an indoor model with no temperature, humidity, calendar, or backlight display. Confirm the exact WT-3102S-INT suffix, rear time-zone buttons, hanger location, lens material, and viewing contrast before purchase. Reception varies by building and distance from Colorado, so check the setup procedure and place the clock where manual adjustment remains practical if overnight synchronization fails.

La Crosse Technology Backlight Atomic Full Calendar Clock with Extra-Large Digits, 513-1419BL-INT

7.7
$52.99
Walmart.com

Overview

La Crosse 513-1419BL-INT is a digital full-calendar clock with nearly 2.5-inch time numerals. It shows time, weekday, and date, and lets the user change the calendar view. The lightweight plastic case has an aluminum-colored finish.

Key Features

  • Seven United States time-zone settings are available for the self-setting clock.
  • The included AC adapter supports a continuously illuminated backlight.
  • Two AA batteries provide on-demand backlighting and are not included.

Considerations

The source does not give total case dimensions, wall-hanger details, normal operation during an outage, signal region, DST behavior, or a manual-setting fallback. Confirm whether the batteries preserve time or fully operate the display, how long on-demand light remains active, and whether a tabletop stand exists. Measure the complete case rather than using digit height as the fit dimension.

$41.99
Walmart.com

Overview

La Crosse 513-1419-WA-INT is a walnut-finish digital full-calendar clock. Its nearly 2.5-inch time digits share the display with weekday and date, and the calendar view can be changed. The body is lightweight plastic rather than wood.

Key Features

  • The self-setting clock supports seven United States time-zone selections.
  • A low-power indicator signals when its batteries need attention.
  • Its durable plastic case has a walnut finish and a lightweight design.
La Crosse Technology 513 1419 WA Atomic Full Calendar Digital Clock with Extra Large Digits, Walnut

Considerations

Do not transfer the BL model's AC adapter or continuous-backlight specification to this WA offer; neither is documented here. Before ordering, confirm required batteries, whether any backlight exists, signal region, DST and manual-setting controls, complete dimensions, hanger, and package contents. The exact 513-1419-WA-INT suffix matters because its finish and stated power details differ from the similar aluminum-color version.

$91.20
Walmart.com

Overview

La Crosse 404-00237-INT is an 18-inch silver analog clock for sheltered indoor or outdoor walls. In addition to WWVB time, its dial includes a thermometer covering 0 to 120 degrees Fahrenheit and a hygrometer covering 1 to 99 percent relative humidity.

Key Features

  • The weather-sealed lens is described for light precipitation and moisture, not heavy rainfall.
  • One AA cell runs the step-ticking movement; two optional AA cells can extend operating time.
  • A time-zone selector, automatic DST correction, and a manual-setting button are documented.

Considerations

Install it in a dry, sheltered location away from heavy rain and direct sunlight, which can shorten service life or distort readings. The movement steps rather than operating silently. Confirm the mounted load, case depth, rear hanger, gauge accuracy and calibration, battery inclusion, and the claimed five-year maximum with three cells. Allow an overnight reception attempt before judging WWVB performance.

La Crosse Technology WT-3143A 14" Atomic Analog Wall Clock, Black

$41.66
Walmart.com

Overview

La Crosse WT-3143A is a 14-inch black analog wall clock with radio-controlled time. Its short listing documents the central setup functions but gives little construction or installation detail, so it is best compared by verified model number rather than appearance alone.

Key Features

  • WWVB reception provides self-setting time from the United States radio broadcast.
  • Four time zones are paired with optional automatic Daylight Saving Time updates.
  • A one-touch zone button is provided, and the clock requires one AA alkaline battery.

Considerations

The source omits case depth, weight, lens and frame materials, battery inclusion, manual fallback, hanger geometry, and any outdoor-use rating. Do not order until the seller confirms the WT-3143A rear label and supplies current front and back photos plus full dimensions. Also check reception for the installation area and keep it indoors unless model-specific instructions expressly allow weather exposure.

$46.97

Overview

La Crosse 404-50447 is a 12.8-inch indoor analog wall clock with a walnut-stained pine frame and protective glass lens. The two-pound round case combines a natural wood surround with WWVB synchronization rather than a printed wood-look plastic finish.

Key Features

  • Four United States time zones and automatic Daylight Saving Time changes are supported.
  • The 404-50447 runs on one AA battery that must be purchased separately.
  • The listed case measures 12.8 inches wide by 12.8 inches high.

Considerations

No complete depth, hanger design, manual-setting fallback, or radio-reception procedure is supplied. Confirm the exact 404-50447 or 404-50447-INT code, frame and glass condition, installed projection, and rear controls before purchase. It is listed for indoor use; avoid humid or exposed placement that could affect the pine frame, and verify wall support for the stated two-pound weight.

$113.45

Overview

La Crosse 433-3256A-INT is a 21-inch bronze analog clock with a textured hammered-metal frame. Its weather-resistant indoor/outdoor design adds integrated temperature and humidity gauges to WWVB time, and the listed wall weight is 6.25 pounds.

Key Features

  • The large round case measures 21 inches wide and 21 inches high.
  • Automatic radio-time updates are received from Fort Collins, Colorado.
  • Batteries are not included, and the listing claims operation of up to five years.

Considerations

Battery information conflicts: the description assigns the five-year claim to three AA cells, while the attributes specify one AA. Confirm the manual and compartment before purchase. Also verify safe exposure to rain, sun, heat, and freezing conditions; gauge ranges and calibration; time-zone, DST, and manual controls; case depth; and a fastener suitable for the 6.25-pound mounted load.

$65.99

Overview

This Amazon offer is another La Crosse 404-00237-INT, the same model code as the earlier Walmart entry. It has an 18-inch silver analog dial, WWVB time, and built-in thermometer and hygrometer scales for sheltered indoor or outdoor placement.

Key Features

  • The thermometer is listed for 0 to 120 degrees Fahrenheit, while the hygrometer covers 1 to 99 percent.
  • One AA cell powers the clock, with space for two optional cells to extend operation.
  • Four time zones, automatic DST adjustment, overnight reception, and manual setting are described.

Considerations

The body calls the clock illuminated once but never explains a light source, control, or power draw, so do not assume the dial lights. Shelter the weather-resistant case from direct sun and heavy rain. Confirm the exact model label, glass condition, three-battery compartment, hanger, 3.8-pound load, gauge calibration, and package contents before choosing between the two 404-00237-INT offers.

Which model number corresponds to each La Crosse clock?

WT-3129B and WT-3129S are 12-inch black and silver analog variants; WT-3102S-INT is the smaller 10-inch silver clock, and WT-3143A is the 14-inch black model. The digital calendar pair is 513-1419BL-INT in an aluminum-color case and 513-1419-WA-INT in walnut finish. Outdoor instrument clocks are 404-00237-INT at 18 inches and 433-3256A-INT at 21 inches, while 404-50447 is the 12.8-inch pine-frame indoor clock. The two 404-00237-INT listings are separate offers for the same model, not two different designs.

Should you choose an analog face or a full-calendar display?

Eight entries use analog hands; their case diameters run from 10 to 21 inches, so wall area and viewing distance vary substantially. The 513-1419BL and 513-1419-WA models instead show time, weekday, and date with nearly 2.5-inch digital numerals and seven zone choices. Only the BL listing documents continuous adapter-powered backlighting and on-demand battery light. Choose analog for at-a-glance hand position or digital when a written weekday and date matter, then verify total case size, contrast, night visibility, and power behavior rather than relying on digit or diameter alone.

Which models add outdoor, thermometer, or humidity functions?

The 18-inch 404-00237-INT and 21-inch 433-3256A-INT are the only models here with both indoor/outdoor wording and integrated temperature and humidity gauges. The 404-00237 descriptions limit exposure to light precipitation and recommend shelter from heavy rain and direct sun. WT-3129B, WT-3102S-INT, and 404-50447 are explicitly indoor clocks; the remaining basic analog and digital models provide no outdoor rating. None of those basic models should inherit weather instruments merely because they use atomic time. Confirm gauge range, calibration, exposure limits, and mounting load for the outdoor choices.

What reception and installation details need verification?

Most analog listings document four United States zones and automatic DST, while the digital calendar clocks list seven zones. WWVB reception is strongest under suitable placement and may need an overnight attempt; manual fallback is explicit only on selected models. Resolve the battery conflicts on WT-3129B and 433-3256A before purchase, and do not copy BL backlight power details to the WA calendar model. For every clock, check the exact suffix, battery inclusion, hanger, depth, wall fastener, lens, zone controls, manual setting, and reception at the address. Outdoor models also need sheltered placement and verified gauge calibration.
