I don't really see anything wrong about referencing the Titus watch in this thread. After all, we are discussing this special category of watches on this Forum and we do sometimes deviate from the specific topic of a thread but it is done in the name of advancing our understanding.

I think I will pass on the Piaget Beta 21 and buy this watch from the same seller:

Patek Philippe 5016 Minute Repeater Perpetual Calendar Tourbillon Platinum | eBay

Hum...I don't think I (or anyone else) needs to be lectured on how forums work and it's not "your" thread now is it! There was no need to post the same message twice in any case ;-) I've seen you do that several times, a problem with your connection, browser?

Anyway, the updated list of spotted B21 brands now stands at :

- Omega : 1300/SS, 1300/18k, 1301/SS, 1302/18k (3 models)
- IWC : SS and 18k
- Bucherer : SS
- Bulova : 18k, round and "pupitre"
- Patek : 18k, several versions called "Cercle d'Or"
- Rolex : 18k
- JLC : movement only
- Piaget : 18k

Still a lot missing : Credos, Elgin, Enicar (Quartz-O-D), Longines, (Quartz-Chron), Rado (Quartz 8192), Universal (Uniquartz); Cyma,Doxa, Ebel, Ernest Borel, Eberhard, Favre-Leuba, Juvenia and Zodiac all called Modul-O-Quartz.



Based on the picture and center "jewel", it looks like an Omega 1302 clone.

I was just pointing out these double posts matter-of-factly to help so calm down. Anyway, rereading the posts in this thread I'm seeing a lot of confusion and it's leading nowhere so I'll leave you to it and hopefully that Beta 21 stem I found for you at CousinsUK will help you enjoy your 10 EACD.

Oliverb "I think I will pass on the Piaget Beta21 and purchase the following from the same seller:

Don't forget, when you get it , that we love pictures. :001_rolleyes:

Aw Jeez, I was really enjoying this thread though not contributing to it due to lack of knowledge and then I go away for a few hours and look what happens. I'm not going to stir the pot but will just say that I think all participants were contributing a lot to the thread and I hope everyone can rub a little dirt into their wounds and move on.
As Rodney King, who was no hero of mine said, "can't we all just get along. "
There are a lot of watch forums out there and I chose this one to join because of the free wheeling non structured exchange of thoughts without mods hovering looking for an excuse to ban someone.

With great advice from Samantha I now know how to remove/insert the stem in the Accuquartz Beta 21 movement. She also suggested I look in the hole for the stem to see if the original stem had broken off. I did and it had. A simple screw removal allowed me to remove a plate and access the stem and I was able to tease out the piece with a screwdriver. Now I'm ready for the new stem when it arrives. Many thanks to Samantha for her help!

I'm with OliverB, anxious to see it. Do you know if it runs ? Is the dial round ?
OK OK, I'll try to be patient and wait for the pictures. :biggrin:

It was good to see this thread revived, it is an all time great one and it was revived for a great purpose.

:thumbup1: You hit a home run with that one, the design, the condition, the bracelet, everything ! A museum piece.
I can only imagine the agony Oliver is going through now wanting a case for his.

I wonder if the folks in the Omega forum would like to see that ?

Wow I'm completely shocked, I never knew Accutron ever made such a model. And when you think $1325 in 1972 would be equivalent to paying $7384.00 us in today's money, it puts things in perspective to who could actually afford such a watch. The Omega is even worse $2,200.00 would be the same as paying $12,260.00 so i think you got yourself a bit of a steal there Peter ;)
I think this is a good example of branding surcharging. Two watches, same movement, same quality of case and yet one is double the price!

I have an interesting wreck of of a watch called a Seiko V.F.A it was the first quartz king Seiko in 1973. On the circuit board it has 21 imprinted on it. Were they copying or paying homage to the Beta 21? It's kinda interesting that it uses dual coils just like a Accutron.

The other odd thing, is why would Omega release the Megasonic in 1973 (Designed by Max Hetzel creator of the Accutron) , if they had already had invested and developed the superior Beta 21?

Hello.
I am from France and new on this forum. May I ask you a question as you are tuning fork specialists:
I have an omega constellation beta 21 just like peterg's one. It runned very well when I bought it 8 months ago. It had a remarkable accuracy. I sent it to a jeweller to get the crystal changed. It had a very little scratch, but the watch was so magnificient I wanted it to be perfect. The case, dial and bracelet are as beautiful as peterg's one; immaculate . I was proposed a new battery as it was opened, so I said OK. (bad idea)
Now it goes too fast (about 5 to 10 minutes per day). The watch is still at the jeweller's and all I can say, is that he tried different batteries (386, 344...) but did not succeed (and of course, he dropped the old battery....). He asked some collegues for advice and recently someone proposed to him a transistor installation on the circuit bringing the voltage of silver oxyde battery from 1.55 to 1.35 V. It seems to be someone working more or less with omega and this person asks 250 euros to do this, with a 1 year warranty .What do you think about this ? Is it safe ?
Could you please tell me which battery you have in yours. Do you have any tip for me ? I really love this watch and I would like it to work properly .
Thank you very much for your help.
And, please, please excuse my terrible english.
Olivier.

Wow, great question! As you may know, all modern watch batteries, no matter the number, are now silver oxide and 1.55 volts. In our Bulova Accutron tuning fork watches the silver oxide 1.55v battery makes little or no difference in time keeping. For some, a slight regulation corrects any difference.

On this forum we are not knowledgeable about the Beta 21 movement. There is a guy in Bulgaria who services Accutrons, the f300 tuning fork movement and says he can service the Beta 21 movement like yours. What has been proposed to you sounds reasonable but you might want to seek out another opinion. His email address is below. If you do contact him, mention that OliverB from watchtalkforums referred him to you. A few of us on this forum have bought Accutrons from him and/or had him service our Accutrons. That is quite a bit of money they are asking for the modification and you should be certain it is the proper thing to do. Hope this helps.
