For sale is a Seiko 9923-500A.

The Seiko Twin Quartz SQ 9923-500A is an extremely rare export version of the JDM Seiko Twin King Quartz.

The watch case and integrated bracelet is finished in fine brushing for a sports watch aesthetic with a polished faceted bezel for increase depth when viewed.

The style of bracelet used on the 9923-500A might remind many of the one used on Patek Philippe's Nautilus thanks to the design of the middle links.

The alluring dark blue sunburst dial is kept highly legible with contrasting white paint added to the hands and indices.

The Seiko 9923 calibre powering this watch is an ultra-high precision watch with an annual variation of only ±20 seconds at the time of production. This precision is achieved by having an additional quartz crystal to assist in timekeeping when temperature fluctuates.

The watch comes on its original bracelet that fits up to 6.75" wrist.
