The official name of the watchmaker Gin is Sinn Spezialuhren (Gin Special Watch Company).

In 1961, Helmut Zinn, a pilot and flight instructor of the German military, started to make watches for pilots under his own name.

He began making watches based on three principles: “the best watches at the lowest cost”, “high quality with the best functionality and legibility”, and “offering value through direct marketing without extensive advertising”.

The brand has been very popular among the people who are familiar with it.

There was a time when it was actually delivered to the German air force, and it was used in the space shuttle mission in the 90’s. The diver model is still used in the GSG9.

Even today, the Diver model is actually used by GSG9 (German Special Forces Against Terrorism) and the firefighting and rescue units.

B series is the iconic model of the brand.

With excellent legibility and a very simple design, it is a very practical chronograph.

It has a black bezel with bi-directional rotation, which is reminiscent of the 155 model that was formally adopted by the German Air Force in the 60s.

SINN 103.B.AUTO.SA, only 200 pieces were sold around 2006.

The watch has a matte black dial with white indexes, whereas the standard model has a white dial with black indexes.

There are a few watches from other brands that have black in-dials, known as “pandas”, but this design is quite rare, as both are white.

The case size is 41mm, but the bezel is smaller than the numbers due to the thicker point of the bezel and its shape, which tapers down to the lugs.

As a comparison, I took a photo of it side by side with the 40mm Rolex Daytona 116500LN, but it’s almost the same or you may feel that the 103.B is smaller.

B may feel smaller than 103.B. However, the thickness is 15.5 mm, so you may feel the weight when you wear it on your wrist.

The backside of the case has the same sapphire crystal as the windshield, so-called back-skating specification.

The movement is based on the Valjoux 7750 and the rotor is decorated with the Côtes de Genève.

There are almost no worries about stopping the supply of parts, and there is no worry about being unable to repair or overhaul the machine because it is easy to maintain.

The bracelet is a three-strand system with a double-locking buckle.

It is originally a very rugged and masculine watch, but because of the white dial, you can wear it with a shirt like the picture on the left, or a knitwear in the fall and winter.

The combination of almost pure white dial with black bezel is very rare, except for Daytona which I compared, and there are one or two kinds of Speedmaster of Omega.

It is one of the best watches for those who are looking for a slightly more beautiful chronograph.

The watch would be completely serviced by our watchmaker after your order.
It takes about 4 weeks to complete. It comes with 1-year warranty.
