This Sea-Gull automatic wristwatch pairs a moon phase display with a calendar and Roman numeral hour markers on a 41mm round case. The ST2108 automatic movement, with 26 jewels and a frequency of 21600, powers the watch through the motion of the wrist, so no battery is needed.
The 316L stainless steel case measures about 13mm thick with a 49.3mm lug-to-lug span, and a synthetic sapphire crystal protects the dial. A leather strap about 19cm long and 20mm wide fastens with a push button hidden clasp, and the watch is water resistant to 5 bar.
