ID Your Watch!

Are you new to Accutrons and don't know what model your watch is? (other brands click here). This chart may help you establish the basic calibre (model) of your watch without you having to open it up.

Important Note: The pics below are only representative of a particular model. There are many variations of case styles and dials, though the basic characteristics of each calibre remain the same.

• Accutron 214 watches are "back set", ie, the time is set by flipping out a semi-circular ring on the back of the watch.
• The battery is accessible from the back via a Battery Hatch which can be unscrewed. The watch-back does not need to be removed.
• 214's do not have a day/date function.

• 218: Time only, with sweep seconds.
• 218D, 2181: Time, Sweep secs., Date display.
• 2182 and others: Time, Sweep Secs., Day and Date display.

• Time setting crown usually at 4 O'clock position (but not always).
• Back must be removed to change battery.
• Date models have "quick change" day function.

As above for the 218. It is hard to distinguish these watches from the 218 series without looking inside, except when they are marked "219" on the dial like the Railroad example shown below. 219's are encountered a lot less often than 218's.
