Tudor Grantour Chrono 20350 - Overview The Tudor Grantour Chrono reference 20350 is a sporty chronograph produced by Tudor (the historic sister brand of Rolex), launched around 2009–2010. It’s designed for those who want an elegant, technical watch with a strong motorsport inspiration — the name \"Grantour\" itself recalls endurance racing. Case: 41mm stainless steel case. A perfect size: sporty but still very wearable every day. Thickness: around 13mm (relatively slim for a chronograph). Movement: Automatic mechanical. Powered by a Tudor-modified ETA 7753 — one of the most robust and reliable chronograph calibers. Dial: Available in black, white, or silver. 3 subdials: hours, minutes, and running seconds for the chronograph. Date window discreetly placed at 4:30. Bezel: Fixed stainless steel bezel engraved with a minute track — ideal for motorsport timing references. Crystal: Domed sapphire, scratch-resistant. Water resistance: up to 150 meters (better than many sport chronographs!). Bracelet: Offered either on a robust stainless steel Oyster-style bracelet or on perforated leather or rubber straps. It\'s one of the last Tudor models before the modern Heritage era — so it keeps that classic, robust DNA. A true mechanical chronograph, reliable and well-proportioned. Fantastic value for money compared to other Swiss chronographs: you get near-Rolex quality for a much more affordable price.
