With its 40 mm stainless steel case, rotating ceramic bezel, and the legendary Seagull ST1901 column wheel chronograph movement, this timepiece offers an exceptional balance of style, precision, and functionality.

Classic Design, Modern Features

Inside beats the renowned Seagull ST1901 manual-winding chronograph movement, featuring 21 jewels, a frequency of 21,600 vibrations per hour (3 Hz), and a power reserve of approx. 45 hours. The fine execution with swan-neck regulator ensures precision and durability. The movement can be admired through the transparent sapphire case back.
