1977 Bulova Accutron ref.nr 21370

Nice ad find; looks to be a match. Not sure we are using the reference number, so I'll call it an Accutron Calendar.

In reply to is the question whether by jabs
Like all other tuning fork movement watches we have, I'm thinking just Accutron Calendar?

probably yes, in the database we have a single Bulova Calendar
You nailed it Jabs. I'm good with Accutron Calendar.
1977 Accutron Calendar, nice job on the advert match
Hey! Thanks everyone.
The watch pictured was a high school graduation gift from my parents in 1977 (the year of manufacture) it is engraved on the back. I will post this soon.
Over the years, the bracelet was lost and I paid no attention to the watch....but kept it.
Well, I kind of got the watch bug.....longer story. So I purchased a back removal wrench, a pin press and a springbar tool. I replaced the battery in the Accutron and WOW it ran. It has gained about 15 seconds in two months. Pretty good according to a watchmaker I met.
I found an exact match on ebay for about 250.00 (double the retail in 77!) and it is on the way. Should be here in a day or so.
I will post photos of the complete piece when it is all together.
And thanks again. Very cool website!
