1989 Seiko/Alba 'Field Gear' Quartz GMT Field Watch (V339-7020)

Very unusual field watch from Seiko JDM sub-brand Alba. Inside the grey PVD steel case with fixed compass bezel is a navy and yellow dial with a four-handed Seiko GMT quartz movement. The second, minute and hour hands work as standard, but the yellow GMT hand allows the user to track an alternate timezone in 24-hour format. Really handy - I've actually been using it to track London time while Wimbledon is on.

In good working order. Keeping time and all subdials work as expected. Case crystal and dial are all in good condition with light wear and light scratching. Dial has some light patina. Caseback has some scratches and tool marks. Fitted to a braided brown leather strap with some wear but plenty of life left.
