The Watch
The cushion-shaped case is made of stainless steel with a micro-blasted finish. It has a diameter of 43mm, a thickness of 11mm, and weighs 85 grams without the bracelet. The watch features a flat sapphire crystal with anti-reflective treatment on both sides. The steel case back is screwed down.
The black dial features a matte finish. It has 2 luminescent hands for hours and minutes and a red seconds hand. The applied bar indexes at every 5 minutes are also luminescent. Two windows are positioned at 3 o'clock to display the day of the week and the date.
An internal, bidirectional rotating bezel runs around the dial. It is adjusted via the crown at 2 o'clock. The crown at 4 o'clock is used to set the time.
The watch comes fitted with a stainless steel bracelet with a deployant clasp.
It is water-resistant up to 10 atmospheres - perfect for swimming, but not designed for scuba diving.
The Movement
This case houses a Swiss automatic movement, the Sellita SW 220-1. This 26-jewel caliber displays hours, minutes, and seconds, as well as the date and day of the week. With an oscillation frequency of 28,800 vibrations per hour, this movement delivers a power reserve of 38 hours.
