The Sea-Gull Moon Phase watch pairs a 41mm round 316L stainless steel case with a leather strap, driven by the ST2108 automatic movement with 26 jewels. A moon phase display anchors the dial, surrounded by synthetic sapphire crystal and a simple, uncluttered layout that keeps the complication front and center.
At roughly 48mm lug-to-lug and 12.5mm thick, it sits flat enough for daily wear under a cuff, while the pin buckle and 19cm strap keep the fit secure. With 5 bar water resistance, the watch is built to handle splashes and everyday handling.
