Just picked up a Speedmaster Professional 3572.50.00 (Hesalite Sandwich) from the 90s that needs its plexiglass replaced. Can someone point me in the direction of where to purchase either a genuine Omega crystal, or an aftermarket crystal that is known to fit? Thanks!

Why are you looking for a replacement? Is the glass broken or just scratched?

If broken, be careful the movement isn't damaged.

If scratched you can just use Poly Watch to repair.

I don't yet have the watch in my hands, but from the pictures there are several extremely deep gouges. Deep enough where they may be full cracks. The seller I bought it from confirmed they just polished the crystal (and unfortunately the case), and this was the best they could get it. Movement seems to be OK, but probably in need of service (watch showing +/- 8s/day depending on position on a timegrapher). The price I paid was commensurate for the heavily used condition.

If the crystal is cracked then moisture, dust, water and even plastic pieces from the damage can be in the movement. Instead of worrying about replacing the crystal, you should be worried about the movement due to the crystal damage. You have no idea what you are in for. I would not buy something like this ever

I would take it to an authorized repair center so you get one with the logo in the center of the crystal, makes a dif in value. Have whoever does the work to check it out and see if it needs a service. Also make sure they install it with the logo positioned correctly.

Just thought I'd give an update - Watch came and cosmetically it was in much better condition than described. I've seen watches with larger crystal inclusions described as unworn.

Unfortunately the hour counter for the chronograph doesn't reset so back it goes (dealer sounded genuinely surprised by this). Says he may be able to source me another 3572.50. Stay tuned.
