Vandaag het derde en voorlopig even laatste horloge van dit jaar ontvangen:
Een Seiko SUS GMT van juli 1997
Eerst een stukje over de Seiko SUS lijn wat ik her en der op het internet gevonden heb.
Geen idee of het allemaal klopt, maar ik vond het wel interessant 
In 1991/2 Seiko had 2 of its design engineers come up with a new line for the digital youth of the day to introduce analogue time!
The designers’ philosophy was this:
- the eye must first draw to the hands for maximum legibility.
- then the eye must hit the dial
- lastly the eye must wander to the bezel, if need be.
This is why all SUS bezels are plain with no distraction. Another common feature was the date at the 4 position.
Another common feature was the square shaped hands. All models tended to be midsized under 38mm wide.
The series lasted for about 8 years. During this time, the SUS line included the often coveted 4S15 mil style (came in black and cream dials) auto, the 4S12 GMT model coming in 3 dial colors (black, blue and red).
Seiko fans will no doubt know, heard about or even handled a watch with the 4s movement, or its predecessor the illustrious Daini 52 movement.
Here’s a brief chronicle of the 4S Series from the NZ timekeeper post.

The two most famous and widely pursued watches containing the modern 4s movements are the SUS military with the basic 4s15 movement and the SUS GMT with the 4s12 GMT movement.
All 4S feature Hi-Beat 28’800 A/h movement, with integrated auto-winding–thinner in profile compared to a modular system, and allows the case to be made thinner.
Thermo-compensating balance and hair-spring come standard with the base caliber, while the higher beat rate (for Seiko) allows it to be adjusted to higher tolerance.
The movement also hacks and hand-winds. The 4S35 is best compared to the ETA 2892 in Top execution, and if it were Swiss, would likely be considered a Tracteur.
Both ETA 2892 and Seiko 4S were not made to be, but rather, born chronometers.
