Additional Information

I picked this up via eBay fairly inexpensively, but unfortunately it's a non runner.  Perhaps a bad coil?  I'm not getting a hum, so I've purchased a spare movement that has a good coil that I'll use to get this one running sometime in the future. 

This one has a nice two tone bracelet that unfortunately has a bit of discoloring despite the excellent, almost NOS condition of the case, crystal, dial, etc.  Nice looking gold colored dial, and quite a looker on the wrist. 

The '79 Supplement #1 ABC Case Parts Catalog info on this watch follows:

Case # GT-3663 / Caliber # 2192.10 / Crystal # 1721M (note says use Narval epoxy) / Crown # 99GY / Gasket # G780 / Back Rim # BR7 / Bezel ring # B310 / Spring bar # 958

Can't argue that one Stephen - Accutron Calendar 21370 it is!

Nice looking watch Eric.

I will.

A model number is a model number and the site is not set up to identify by, nor have We been using individual model numbers for identification purposes.

'ACCUTRON' Calendar - variant unknown.

The Bulova model numbers have not been used as model names, but sure may help us determine a model name (or variant).  Pretty sure there was a model name in 1977.  The ad Admin linked above has numbers which may have been used for folks to order a particular model, and simply not mentioned the model name (or variant).

Was Admin suggesting 21370 for a model name or variant?

Accutron Calendar (Bulova number 21370) model name/variant unknown...for now.

An update for this watch - I haven't been participating here for awhile, and someone at the forum contacted me about this watch.  I visited the original post and noted that I'd put it down as not running.  Member Accutronitis repaired this watch years ago, and it's been running solidly ever since.

I have a  21370 Accutron watch as well and am looking to get a new strap for it. What is the millimeter width that I should be looking for?

The best way to know is to measure the space between the lugs (the place where the strap attaches). That measurement will give you the size you need. A jewelry store should be able to help.
