Up for sale is a SEIKO automatic diver 6309-729B. This is the harder to find orange dial version from my personal collection. As far as I know, this is the first SEIKO automatic diver with orange dial.

- Thickness: 13 mm.
- Lug: 22 mm.
All-original except for the crystal retainer ring which has been replaced with genuine ring taken from other SEIKO 6309 diver.
Original dial is in good condition.
Original golden hands have oxidations.
Lumes on index markers, hands, and bezel insert still glow faintly and fade at the same rate.

All gaskets (crystal L-gasket, crown, caseback) have been replaced with brand new SEIKO genuine gaskets on July 2010. It is not pressure tested so water resistant is unknown.
