Sinn 103 Sa G - The traditional pilot chronograph

Reading Time: 2 minutes

Sinn 103 Sa G is a traditional pilot chronograph with an extraordinary design. Its eye-catching features include the dial in shimmering metallic-green, the green bidirectional rotating pilot’s bezel in anodised aluminium and the day and date display, also in green. This colour scheme is applied consistently throughout, providing the timepiece with an aesthetic balance.

Another special feature is the high-quality crystal. Here we use a high-domed sapphire crystal glass with a profile similar to that of traditional acrylic glass. Using specially made grinding tools, the sapphire crystal glass is ground out of a solid blank approximately 5 mm thick with five different curvature radii and is then carefully polished. This complex process offers outstanding benefits, making the sapphire crystal glass highly resistant and maintaining the classic appearance without losing the functional character of the watch.

Sinn 103 Sa G is limited to 500 pieces, which is documented by the ‘Eine von 500’ (‘One of 500’) engraving on the transparent back ring. This timepiece is, of course, resistant to low pressure and waterproof and pressure-resistant up to 20 bar.
