103 Ti Ar Chronograph Watch

The Watch

The Sinn 103 Ti Ar pilot chronograph proves that cutting-edge technology and functional design can combine to create a true classic. The case features a micro-blasted finish in pure titanium, reinforcing the watch's technical and contemporary identity. It measures 41mm in diameter and 17mm in thickness. A pilot-style fixed bezel with minute ratchet and luminous markers completes the round case. A screw-down crown at 3 o'clock handles time, date, and day adjustment, while two pushers make operating the chronograph intuitive. The dial is shielded against shocks and scratches by a sapphire crystal with double anti-reflective coating. The screw-down caseback is transparent, also fitted with a sapphire crystal, offering a striking view of the movement in action. Water-resistant to 20 ATM.

The Dial

The round, elegant, and timeless dial features a matte black finish. Arabic numerals and baton indexes coated in luminescent color give the watch its sporty character while ensuring optimal legibility. At the center, three cathedral hands - for hours, minutes, and seconds - are also luminescent. Three subdials serve the chronograph function: a 12-hour counter at 6 o'clock, a small seconds counter at 9 o'clock, and a 30-minute counter at 12 o'clock. A rectangular aperture at the 3 o'clock index displays both the date and the day of the week. The brand's signature appears just above it.

The Movement

At the heart of this model beats an automatic movement - the Concept C99001 - featuring 25 jewels and running at 28,800 semi-oscillations per hour. This caliber also offers a stop-seconds function and is antimagnetic per DIN 8309.

The Strap

This model comes fitted with a silver stainless steel bracelet. Elegant and durable, it delivers optimal comfort and a secure fit. The bracelet features a 20mm lug width and fastens with a butterfly deployment clasp in gray stainless steel.

Water Resistance

With a water resistance of 200 meters - that's 20 ATM in the precise language of watchmaking - this watch is built for recreational diving. It can handle showers, baths, and open-water swims, including shallow recreational dives (free diving). For professional scuba diving with tanks, our Ocarat watch team has handpicked a selection of 30 ATM models available in the catalog - just run a quick search on our site. One last word of advice before we let you enjoy it: never operate the pushers or crown while the watch is submerged.
