Seiko's Quartz Chronograph was delivered to the Royal Air Force ( Royal Air Force / RAF) and adopted by the Royal Air Force ( Royal Air Force / RAF). There is a model that has been.
The chronograph equipped with Cal.7A28 was delivered from 1984 to 1990. Generation 1 ( 1st generation) is an abbreviation for Gen1.
The successor model equipped with this Cal.7 T27 was delivered from 1993 to 1997, and is called Gen2, which is an abbreviation for Generation 2 (2nd generation).
The one that was actually delivered to the military and used has a broad arrow mark and a military code engraved on the back cover, but since this individual is a so-called "commercial item" that was sold to the general public. The back cover contains only the usual engraving.
It is a design that is not too rugged while having robustness and visibility that clears the specifications required by the British Ministry of Defense.
Therefore, although it is a military watch, it is a watch that also fits a leather belt.
The case size is 38mm, which is a small size for a chronograph. This size isn't quite there.
The case is sandblasted (pear-skinned) to give it a matte texture.
The dial is a black dial with a sandblast finish similar to the case to suppress light reflection.
SEIKO indicates that the luminous paint uses promethium.
Promethium is a luminous paint used by Seiko from the 1960s after radium until it was replaced by Luminova.
It has properties similar to tritium, but has a shorter half-life than tritium.
A 30-minute counter is laid out at 12 o'clock, a small second (second hand) is laid out at 6 o'clock, and a 24-hour counter is laid out at 9 o'clock.
Because it is a quartz movement, it is a good point that you can use it without hesitation compared to a mechanical chronograph.
Also, the thickness of the watch is suppressed and the weight is not so heavy, so it is recommended for everyday use. The
strap is a NATO strap from Singapore's STRA Space brand.
It is a design that can be said to be a NATO strap with the ruggedness removed because it is slightly glossy and has a herringbone pattern.

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.
