Sea-Gull Vintage Retro Tonneau Calendar 36mm Automatic Watch
This Sea-Gull automatic watch pairs a tonneau-shaped 316L stainless steel case with a silicone strap, giving it a retro TV-dial look that suits casual wear. The 36mm case and 40mm lug-to-lug span fit a range of wrists, while the synthetic sapphire crystal protects the dial.
The ST2100 automatic movement runs at 28,800 vibrations per hour with 28 jewels and a 42-hour power reserve, and the calendar function keeps the date on hand. At 5 bar water resistance, it handles everyday splashes and brief contact with water.
