I View attachment 1097853 View attachment 1097853 Hi
I couldn’t resist taking this duo of 1970s Geneve Dynamics home from a house clearance sale. It looked like the owners whole world was on show and I’m guessing these were bought as his and hers ‘cool’ back fifty years ago
So here is my question(s)
I would like to improve them with new crystals and possibly new straps and keep them together but although I really love the unique look there is a limit on my budget and one phone call to my restorer may have just blown it!
He quoted £300+ for a couple of glasses plus servicing etc Could be £700 or more

Now I know that the replacement involves puffing air into the crown barrel and I think I’m comfortable with this. But has anyone had success with this? Once off does the replacement fit easily? Finally where can I source a decent quality replacement?

And a last question-
The strap on the ladies is beyond redemption but the original blue branded one on the gents is still wearable and has responded to feeding but am I better buying a modern replacement and wrapping the original up as part of its provenance ?
After all of this and in great condition do I have £800 to £900 in value between them?

Not all about money but I guess it’s nice to stick to a sensible budget
Thanks for reading and any dynamic reading matter would be much appreciated
Cheers

Best shop around for more reasonable quotes for crystal replacement and service. The straps are available fairly reasonably online as many aftermarket people make them and they usually are very good quality and inexpensive 😀

The stainless bracelets also pop up for these- you really can’t miss them when you see them as they have the case ring built-in.
I think these are incredibly cool watches and even more so as a his/hers pair.
Unless the crystals are cracked or crazing, I see no reason why they would need replacement- polishing them out would make them crystal clear again.
If you’re watchmaker is suggesting the puffed air trick. then I expect he isn’t familiar with these watches- and if he’s not familiar with them, then he may not have an Omega parts account- and if he does not have a parts account.......

Just make sure you keep the Omega buckles and put them on the new straps, because those are hard to find now.

The dials are on the lower end of average condition from my observation of the market, but the men's size and bullseye dial makes it one of the more desirable combinations. The ladies models fluctuate between $150 and $400 depending on time of year/etc and the men's models tend to be around $400-$800.

Thank you all for your brilliant feedback
Really can’t find much evidence of the ladies with red sweep and this dial

And a point on your watchmaker- if he does have access to factory parts (including crown which should be changed as a matter of caution due to deteriorated gaskets) and is capable of doing a proper service- £300 for a service with factory crystal and crown isn’t bad- the crown and crystal alone would account for £100 of it (Omega crystals can be $$). He CANNOT use generic crystals and crowns on these, it will compromise any waterproofing- even a mist or sweat could cause a problem- you need to verify that he will use only factory parts or go elsewhere

They crop up. I've seen at least one on the Bay in the last year, though I think it might have been on the bracelet.

As Fred has said, non-Omega straps for these are available very reasonably. These pieces are very fun to wear and surprisingly comfortable. Definitely worth servicing to get the best out of them, but giving the crystals a good going over with Polywatch should bring them back to glory.

Desmond's excellent essay on these can be found linked on this page of his blog. It’ll provide the good reading you’re after.

Enjoy your Dynamics!

Nice find! I think the men's Dynamic may need a crystal swap based on the crack at 1230, but I've been able to have a crystal swapped with an Omega signed replacement for about $50 plus $250 for a service. The ladies Dynamic appears to be in better shape.

I've been able to source an Omega #27 deployant for the Dynamic on Ebay, and in addition to the aftermarket bands, I was also able to purchase an Omega black strap for 102 pounds and an Omega 14mm buckle for 21 pounds from CousinsUK in 2019.

Here's a picture of the deployant:

Many thanks
Fortunately I have both original buckles so just exploring strap options
Can get aftermarket copies which do the job but am also considering custom homages in hand finished leather so that both match
But radical for me but what do you think?
After all the Dynamic was never a conformist....
Cheers

Custom straps are the way to go on these. Even if you find NOS they can be brittle and have limited life- plus, why would you want to tear up a NOS strap??
Find a strap maker and send him the originals to use as a template- and have fun with color as these watches were not meant to be subtle.

Just make sure the leather isn't too thick, otherwise you'll never be able to get the screw ring to attach properly.
