For sale is a slightly used aftermarket sapphire exhibition caseback for the Omega Speedmaster from Spiralwinder Watch Parts. I used it for about a week on my FOIS and went back to the OEM caseback. I put protective stickers on both sides of the sapphire to store it for later use but haven’t had a need, so it’s up for grabs.

Fits most Speedmaster Professional models other than the 3861 and a few limited editions. Check out the Spiralwinder website for more info if needed.

Sold complete with both the caseback and the gasket/spacer as shown.

$55 delivered CONUS, payment by Wise, Zelle, or PayPal.

Thanks for looking, and as always Thank You to OF for the space.
