#790 Sapphire Exhibition Caseback ONLY for the 3861 Omega Speedmaster

After months of intensive development and weeks of rigorous testing, they have finally arrived!

Got a 3861 Speedmaster Professional Moonwatch, and want to see that Co-axial Master Chronometer movement while making your watch more ergonomic? Swap out the solid caseback with this precision-engineered ultra-thin exhibition caseback, and be able to view the movement at your leisure!

Revolutionary Form:
This new caseback continues to push the boundaries of what is possible. We have carefully engineered an inverted double-bevel profile that reduces the steel volume, allowing the caseback to virtually disappear into your wrist. Of course, it wouldn't be a SWP caseback without an overall reduction in height. This new profile, meticulously optimized for slimness, will reduce your 3861 Speedmaster height by approximately a quarter of a millimeter.
