Sinn bestows a metallic blue dial on its classic 103 pilot’s chronograph with the 103 A Sa B limited edition, featuring a steel case equipped with the brand’s patented dehumidifying technology.
The quintessential Sinn pilot’s chronograph, the 103 has been in the catalogue since the 1960s when Helmut Sinn founded the company. It’s functional and legibly, typically powered by the ever reliable Valjoux 7750 movement. Keeping the classic look but with the added flourish of an electroplated blue dial, the 103 A Sa B is limited edition of 500 pieces. The “A Sa B” suffix in the model name stands for “Automatik Saphir Blau“, which translates as “Automatic Sapphire Blue”, explaining many of its features. Finished with a sunburst brushing and electroplated a metallic blue, the dial has silver counters, a look reminiscent of the discontinued 203 Arktis chronograph designed for Arctic explorers. It’s the second Sinn introduced this year with a blue dial, after the T1 and T2 B dive watches.
The case is steel, 41mm in diameter with sapphire crystals front and back, and water resistance of 200m. Inside is a Valjoux 7750, visible through the display back, with the individual edition number on the rotor. The case is filled with inert argon gas to keep moisture out, a patented feature calls Ar-Dehumidifying Technology.
The 103 A Sa B is presented in a box with both a blue cowhide strap and a grey NATO canvas band. It is priced at US$2230 before taxes, or S$4600 with 7% tax.
