EON “Sailmaster” Mod – Modified Casio WS-1700 in Full Metal AE-1200 Case – Moon Phase, Tide Graph – Light Blue Strap – Custom Casio Watch - ae1200

The EON “Sailmaster” is a one-of-a-kind hybrid: a genuine Casio WS-1700 re-housed in a fully CNC-machined 316L stainless steel AE-1200 case — often known as the “Royale” body. This transformation gives the robust tide and moon phase tool a sleeker, more wearable form, while preserving all original WS-1700 functionality.

To complete the build, we’ve added a silver faceplate, hand-finished in our workshop, plus custom 18–22mm adapters and a soft light blue suede EON strap for an understated nautical look.

This model is especially well-suited for outdoors, travel, and maritime environments — offering moon age tracking, tide graph data, and multiple alarm types in a premium-feeling steel frame.
