20 Most Recent La Crosse Technology E. Howard Ambassador Radio Controlled watch Questions & Answers

This is the model with the exposed button on the right side. The back does not come off, but the front does! If you use a loop you may be able to see a notch between 7 and 9 O'clock. Be very careful because the gasket keeping the watch water resistant is right there. You do not want to harm it. I put the watch in a holder and place a very thin jewelers screw drive on the side. With a jewels hammer I tap lightly until the front comes off. You must then carefully remove the movement from the case and not touch the hands. In order to close the watch after battery replacement, a watch press is a must. Without the press, you won't get the watch closed. The manufacturer suggests taking the watch to a qualified professional. You can send it to the manufacturer as well and they will change the battery for you. The Manufacturer is La Crosse Technology in La Crosse Wisconsin.

you can get the crystal off, but not back on. There is a special tool that is used to compress the crystal to make it fit in the bezel. Besides, if a piece chipped off, it is no longer waterproof. Take it to a jeweler and he can put a new crystal on in no time. Crystals are not expensive.

when you have an expensive watch, take it to a jeweler or, to a pawn shop. Many pawn shops change batteries, and are cheaper than jewelers. Always ask for price first.

If it has a screw on back you will need a special tool, but if not just a small knife will do it

Yes the battery needs to be replaced. The battery should be replaced by trained personnel to avoid damage and to maintain the water resistance according to factory specifications. After battery replacement the hands of your atomic watch must be repositioned to 12 o’clock. The hands can be advanced either incrementally by repeatedly pressing the T2 button or rapidly by holding the T2 button. Pressing the T2 button briefly advances the minutes, holding the button down lets the minute hand move continuously until the T2 button is released. (The minute is also shown in the LCD helping you to set the correct time.) Your watch now uses its integrated quartz movement. Please note in this mode your watch cannot display the date. The time you have set is retained until your watch is able to receive the signal from the WWVB transmitter again. The date will then also be set and displayed in the LCD again. After your atomic watch automatically receives the WWVB signal the watch will be set to Pacific standard time. You must then either press the T1 button to confirm the time or set the desired time zone. ---------------- La Crosse Technology, Ltd provides a 10-year limited warranty on the movement of this product against manufacturing defects in materials and workmanship.

The back does not come off (case is in one piece); it's the bezel -- the metal rim that holds the front glass crystal.

There is a small notch in the rim of the bezel (on mine, this aligned with the 'lower left' lug on the case around 7:00 on the face). Be careful as there is an O-ring to waterproof the watch, and this notch goes right into the groove where that O-ring is located. Use a case knife or similar stiff but fairly thin-edge blade to pop the bezel off (it snaps off). Then gently remove the outer plastic ring, noting carefully how the notches are aligned.

The inner module now can be lifted carefully out - the two 'pushers' will not fall out of the case when you do this. The battery is a 3V lithium CR2025, and you will need a fairly small straight-blade jeweler's or optician's style screwdriver to remove the one screw that holds down the battery bracket - it may be tempting to bend this out of the way to change the battery, but please resist that temptation...

Put the module back in the base, put the ring back over the dial plate, and carefully snap the bezel back in place with its notch aligned as you found it. You might want to check and/or lubricate the O-ring as you do this.

Instructions for initializing the movement are printed inside the case: they list the switch for the 'recessed' button as A, and the pusher as B. In case you didn't note them before closing the case: to reset:

1) push A once. (Display will read "SET"
2) Push A until hands are exactly on 12:00 (and display reads "12"
3) Push B once to start reception

You then follow the standard procedure of putting the watch in a window facing Fort Collins, Colorado, until it picks up the time signal and synchronizes itself.

If you need more assistance with the physical module, there is contact information on it from its manufacturer:

Model number on my module is AR600 WWVB (37.5mm)
