Conditon : Pre-owned; Very Good to Excellent Condition. 43mm diameter excluding crown, 37mm lug-lug (52mm with the adaptor), 13mm thick; 18mm lug width (23mm quick release lug adaptor).
Accessories: Original stock quick releast 23/18mm bracelet; No box/paper/tags. Water Resistance: 15 Bar (150m). This watch was manufactured in 1992 as a #675 of a 2500 limited edition series. Here we have a very high end quartz watch: it was quite audicious back in the 1990s as Seiko wanted to celebrate it's best quartz technology since they started the revolution in 1969.
There's a lot going on in this watch - sapphire crystal is in excellent shape with no chips/scratches. Minimal scratches on the case and caseback and a custom colored medallion is in place along with a limited edition marking; caseback is secured with a screw-down ring.
Dial has a beautiful as a speckled silver background with gold subregister trim; slight fading on the gold subdial markings due to age. Lume is medium strength on the hands and hour markers.
Unique asymmetric unidirectional rotating bezel is a tad stiff due to age but rotates completely. The 1/100 chronograph works well and resets to zero properly and the buttons are not sticky. Day of week is only in Italian so I think this watch was made for the European market. The bracelet has minor wear on the gold plating but is well built and comfortably fits my 7.5 inch wrist; there are no extra links but I would say it would definitely fit any wrist less than 7.25 inches if you wear your watches loose. The lug-adaptor allows quite release of the bracelet; I don't have the extra straps that came with the watch but you could size up a 18mm strap to fit into the adaptor.Watch is keeping good time and battery less than a year old; service, however, recommended for all vintages. This watch has very good heft on the wrist and is overengineered to the hilt!
