The official name of SINN is Sinn Spezialuhren (Sinn Special Watch Company).
In 1961, Helmut Sinn, a German pilot and flight instructor, took his name on the brand and began making watches for pilots.
Three principles: "Making the best watch at low cost", "High quality and best functionality and visibility", "Providing valuable products through direct marketing without relying on a wide range of advertisements" We are making watches based on.
As a brand known to those in the know, it has been very popular until now.
In the 90's, 142.BS was also used in the Space Shuttle mission, partly because it was actually delivered to the German Air Force and NATO Army.
Even now, the diver model is actually used in GSG9 (Germany's special forces against terrorism) and fire rescue units.
This 103.B series is a model that can be said to be the icon of such a gin.
With excellent visibility and a very simple design, it gives the impression of a practical chronograph.
This 103.B.AUTO.POL.TY model uses a smooth bezel instead of a black bezel and features a neat appearance. In addition, the inner circumference of the dial is equipped with a tachymeter and a pulse meter.
There are some cracks in the luminous paint, but since it is tritium, the hands are left as it is without replacement.

In order to achieve this, the presence of a skilled repair craftsman is essential.
How well the work is done depends largely on the thoughts of the craftsman.
The watchmakers who Arbitro asks are craftsmen who do not cut corners in such areas, so we ask them to carry out the repair work with peace of mind.
About Complete Service
Complete service, sometime called overhaul is the work of disassembling a mechanical product down to its individual parts, cleaning and reassembling it to bring it closer to its new state of performance.
Roughly speaking, the overhaul procedure is as follows.
1. Separate into case and movement
2. Disassemble the movement
3. Inspection and pre-cleaning of wear condition of each part
4. Wash parts with a special machine
5. Lubrication and assembly
6. Waterproof test
7. Final adjustment and running test.
Some movements are made up of hundreds of parts, but it is a very meticulous process of disassembling them one by one, inspecting them all, cleaning them, and reassembling them.
If you don't overhaul, the oil will deteriorate just like a car, and the risk of wear and damage to parts increases, causing a decrease in accuracy and, in severe cases, not working.
There is also the reason that it will be very expensive to replace parts after they are found to be damaged, so we recommend overhauling once every 2-3 years for economical and long-term use.
About Polishing
Vintage watches have been used for decades, and even the stainless steel used in many watches has rounded corners that were originally sharp, and has many small scratches even though the mirror finish should be beautiful. state.
At Arbitro, some watches are sold with a new finish, based on the idea that you can purchase them in beautiful condition and use them for a long time.
In particular, gold-cased dress watches are finished to bring out the best of the precious metal case.
The watches sold by us that have been given a new finish are shot in very high definition, so you can see that the edges stand out and the light is reflected by the mirror finish.
Also, depending on the case or bracelet, there are cases where multiple finishes such as mirror finish and hairline finish are mixed, but there are not many craftsmen who can distinguish between them and finish them at a high level.
In addition, the “thinness of the case” is also a part that is greatly influenced by the skill of the craftsman.
A watch that has become thinner and has thinner lugs is far from its original design, and the appearance becomes unbalanced.
It is a very precise work that brings the case closer to the original finish by eliminating scratches and dents while reducing the thickness of the case to the utmost limit.
Of course, there are cases where it is better to use the watch as it is, in order to emphasize the history of the watch and its original condition.
We look at each watch and judge whether it is best to finish it before selling it.
