Sea-Gull Natural Series Polaris Sub Dial Luminous 40mm Automatic Watch
This Sea-Gull Natural Series automatic watch pairs a 40mm round 316L stainless steel case with a matching 316L stainless steel bracelet and a synthetic sapphire crystal. The Polaris sub-dial and luminous hands keep the dial readable, while the ST17 automatic movement with 17 jewels and a frequency of 21,600 vph drives the timekeeping without a battery.
At roughly 10mm thick with a 46.3mm lug-to-lug span, it sits close to the wrist, and the push-button hidden clasp keeps the 20mm-wide bracelet secure. It is water resistant to 5 bar, making it suitable for everyday wear, and it arrives in a gift box edition with a 1-year warranty.
