Since its founding in 1961, Sinn has focused on high-quality, mechanical watches. When certified engineer Lothar Schmidt acquired the company in 1994, he ushered in a new era of technological development. The list of innovations is impressive.

Key functions and clarity are the all-important features of Sinn. With its classic design based on traditional styles, the 43 mm diameter of the 240 St is distinguished by those unique characteristics which mark it clearly as a Sinn watch. These include a resistance to low pressure and pressure resistance up to 10 bar. The interior pilot's bezel with luminous triangular main marker enables precise monitoring of defined periods of time. The case made of bead-blasted stainless steel features a sapphire crystal glass. Perfect readability, even at night, is ensured by the luminous hands and indices. The 240 St also features the date and weekday, which can be displayed in German or English simply by adjusting the crown.

This great Sinn is in near mint condition and comes as a full set.
