My officemate one day handed me a broken dive watch manufactured by a relatively obscure company named Scuba Pro. He already had several dive watches and thought I might make good use of it, knowing that I collect military dive watches, not that Scuba Pro was any military issue. Nothing was free however. He had traded the original dial, hands, and movement to another watch collector, so basically it was just the case that was handed to me. It didn't matter as much; I had a spare Marathon field watch waiting for such project!

As you can see from the photos, I had the Marathon dial and hands transplanted over the Scuba Pro case, and installed hacking 17 jewels automatic movement. The case is quite heavy, and much thicker than CWC RN dive watch. Crown and caseback are screw down type for water resistance. Bezel turns counter clock wise and clicks like a charm. The band that came with the watch was a cheap looking rubber strap, so I fitted a 20mm black nylon band on it instead, and voila! Ain't it cool?!
