    Anyone know the case numbers for the two watches above? I'm looking to buy replacement crystals for each of them from Ofrei (or eBay?).

    From what I know, the Dynamic Chrono is 175.0310, while the Speedmaster is 145.0022? However, it seems that the crystal for the 145.0022 is 063PZ5078, which is a white/silver tension ring, but I believe the 3572.50 I have comes with a black tension ring, which would've been 063PZ5139?

    Thanks for the help!

    For the 35725000, front crystal is 063PW5139, and back crystal is 062SN0535. Front crystal is the same for all modern acrylic Speedmaster Pros.

    Crystal for the Dynamic chrono is 062SA2056.

    Cheers, Al

    Does anyone know where I can purchase the 062SA2056? It was on Ofrei and I ordered it, but they told me they're out of stock now :(. Thanks for the help.
