Sports Watch 105 St Sa W

The Watch

Discover the stunning 105 St Sa W by German watchmaker Sinn. True to the house's DNA, this sporty, contemporary piece will captivate watch enthusiasts. The round micro-blasted steel case measures 41 mm in diameter and 11.9 mm thick - boldly masculine proportions. A scratch-resistant black bezel crowns the case and serves a dual purpose: a unidirectional minute scale for timing, and a bidirectional 12-hour scale for tracking a second time zone. At 3 o'clock, a screw-down crown lets you set the hands and date. The dial is shielded by an anti-reflective sapphire crystal. Rounding it all out, the watch is water-resistant to 20 atmospheres, thanks to a screw-down caseback - transparent, so you can admire the movement inside.

The Dial

A beautiful round dial sits at the heart of this watch. Its white color brings radiance and brightness to the wrist. The perimeter features a railroad minute track, complemented by baton hour markers. Two baton hands and an orange "Breguet" seconds hand sweep across these markers. For even greater readability, a dual date window sits just above the 6 o'clock index, displaying both the date and the day of the week. The hands and indices are coated with a luminescent treatment so you can read the time in the dark. The brand signature is displayed beneath the 12 o'clock index.

The Movement

Powering this watch with precision and reliability is a Swiss-made automatic movement. The caliber SW220-1 drives the hands and date window with every movement of your wrist. Built with 26 jewels, it beats at a frequency of 28,800 vibrations per hour and delivers a power reserve of 38 hours.

The Strap

A stunning black calfskin leather strap frames the case on both sides. Its orange contrast stitching adds a modern edge while maintaining a quality finish. A grey pin buckle ensures a secure, comfortable fit. Note the 20 mm lug width.

Water Resistance

With its 200-meter water resistance - or 20 ATM, for those who prefer the crisp, technical language of watchmaking - this watch is built for recreational diving. It can handle showers, baths, ocean swims, and shallow, non-professional dives (including freediving). For professional scuba diving with tanks, our Ocarat watch team has curated a selection of 30 ATM models available on our site. One last word of advice: never press the pushers or operate the crown while the watch is in contact with water!
