Seiko Tank 7430-4000

The Seiko 7430-4000 is a wristwatch model produced by Seiko with a "Tank" design. The term "Tank" indicates that the case shape of the watch is rectangular or square; this design was inspired by tanks and became especially popular in the 1920s. This model, which is very popular because it is very similar to the Cartier Tank model, is a product of approximately 40 years and it is becoming more and more difficult to find a clean one on the market. The product you are reviewing was produced in 1986 and is 39 years old.

PROFESSIONAL FULL SERVICE. Since the mechanism is completely disassembled, each part is cleaned, oiled and its sensitivity is adjusted, your watch will work without any negative surprises. (It does not require maintenance for 5 years unless exposed to adverse conditions.)
