-Description
The official name of SINN is Sinn Spezialuhren (Sinn Special Watch Company). The company was founded in 1961 by Helmut Sinn, a German military pilot and flight instructor, who named the brand after himself and started making watches for pilots.
This is the Navigation Chronograph, model 903. You may think it is similar to Breitling's Navitimer, but there is a story behind it.
In the 1970s, Breitling was on the verge of bankruptcy due to the so-called “quartz shock” that hit the Swiss watch industry, triggered by a quartz movement made in Japan.
Sinn bought the design rights to the Navitimer, as well as the movement and other supply lines, and became Breitling's savior.
Although there are some minor differences in the bezel and other parts, this is a rare watch with the same design sold by two different companies.
This 903 St. GL was released in the 1980s and is equipped with the Lemania Cal.1873. A 24-hour version with a Lemania 1877 was also sold at the same time.
The case size is 41 mm and the thickness is 13 mm. The crown is not screwed down, but simply pulled. One of the features is that the transparent caseback.
One of the major differences from the current model is that the inner dial is more centered. The overall condensed design can be said to be unique to vintage watches.
The movement is Lemania Cal.1873 with manual winding as mentioned above. It is the base model of Cal.861 installed in Omega Speedmaster, and is known as a very famous chronograph movement.
There are very few watches with the Lemania 1873 in the Sinn model, so it is a rarity in that sense.
The watch comes with the original leather strap with some signs of use and the original steel buckle.

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.
