Rolex founder Hans Wilsdorf launched the Tudor Watch Company in 1946 in an effort to offer the public reliable timepieces at affordable prices. Since 2015, Tudor has been manufacturing in-house movements to much acclaim.
 

Vintage Sport Line timepieces by Tudor were much celebrated for their power, both inside and out.

First, the cushion-shaped case is comfortable to wear and measures 41 mm in diameter, 14 mm in height, and rests upon a rubber strap with a folding clasp for added safety.

You will notice a convenient tachymetre scale for measuring speeds upon the bezel. Additional features include a 150 m / 15 atm water resistance, screw-down Triplock winding crown, closed caseback, and scratch-resistant sapphire crystal.

Under the hood we encounter a robust caliber: the self-winding automatic Valjoux 7753, which possesses 27 jewels, delivers around 48 hours of power, and has a hacking / stop seconds feature when setting the time. 

This chronograph caliber gives you a center seconds hand, a small seconds counter at 9, a 30-minute counter at 3, and a 12-hour counter at 6. Note how the date window seamlessly works its way into this subdial. In addition, the quarter-turn chronograph pushers result in a nice sleek pusher design.

The black-colored dial serves as a lovely backdrop for easily reading the time via stylish baton hour markers. Luminous hands and markers come in handy in low light.
 

From its powerful chronograph caliber to its sleek and sporty stylings, we encourage you to add this Tudor Sport Line Automatic Chronograph to your collection today.

Standout feature(s): Robust Valjoux 7753 chronograph caliber with hacking / stop seconds; convenient tachymetre scale for measuring speeds; screw-down Triplock winding crown.
