Hi all,

I've inherited an old vintage watch from my grandfather, containing the name 'Betra' on the dial. It appears to be a watch made in the 50's or 60's (?) and furthermore bears the words automatic, 22 rubis, incabloc and swiss on the dial. It has a small diameter (+/- 35 mm incl. crown and 16mm strap width), but that's about all I know...

I couldn't find anything about the model, time-piece or even the brand on the internet; is there anybody who knows some more about it or knows somebody that might?

Thanks in advance!

Interesting piece, Is it possible that You can make more pictures including the movement?
I also believe in the 50's style.

Thanks for your replies! I'll continue my search and contact an Amsterdam based vintage watch store; see if they can help. Maybe there's someone else on this forum that might know something about it.

@ armian: I'll ask the watch store if they can help me regulating the movement and I'll try to make some pictures too.

Is it btw unusual for a watch like this (that has probably only seen the inside of a case for years ;p) to run about 35 seconds late per day?

Hi,
That will be nice of You.
In accordance to unknown date of the last service - It is only 35 s late-for some of mine Soviets at least a minute is standard and that is it.


Regards
aRm

Yes aRm and Woeter the movement will give the answer. You can't compare the stand of technique of average mechanic serial movements probably 50 years ago with a high quality modern one. For my feeling some seconds are a very good mark even for a good movement but it depends on the quality of the movement inside this watch what you can appraise. In each case a service is nessesary for a watch who lives in a case over many years. The oil is gone or decomposed and if you wear it "dry" you'll irreversibly damage it within a short while. Therefore You've done the right thing.

Kind regards Silke

Totally agree, it is a terror to keep it working dry and dirty.
Interesting, I guess it could be Felsa automatic cal. but it is only guess.

I will probably let someone service the watch, put on a new glass and chrome the case. I'll try to get photo's of the movement to; keep you posted.

Hi guys!

It's been a long time since I posted about my grandfather's Betra watch. Since then, I've had a reply from a Dutch used watch store in Amsterdam. They told me that there were stores during the 50's that had dials designed with their own names on it, therefore Betra could have been the name of a local watch store..! Furthermore, it has been serviced by a professional watch maker, who also completely polished the case and added new chrome patina. The plexiglas has also been replaced. The movement is a Felsa (so you were right armian!), I don't know the exact type, but I guess it could be a bidynator (since you clearly hear the moving sound of the rotor). See the enclosed pic of my serviced watch!
