Out of my own watch box, a very nice and original 6309 150m diver. Fully serviced, case rebuilt with all new seals, movement upgraded with upper & lower mainspring arbor jewels.

• Fully serviced 6309A movement in great original condition.

• Movement upgraded with upper & lower mainspring arbor jewels

• All case sealing surfaces are clean and undamaged, and all seals have been replaced

• Case has been lightly rebrushed on the upper surfaces. Lower surfaces & caseback show signs of use - swirlies, small marks - but no abuse. No tool marks on the caseback.

• New KVW 320W34GN00 crystal in place

• Crown screws down completely and firmly - no binding or cross-threading

• Rotating ring clicks bidirectionally 360º. Insert is espexially nice, with a good clean pip.

• Dial lume is a slight butter-cream tan, rare to see in a ‘79 as it’s more of an early feature.

• Dial resist text is faded to gray.

• All dial printing clean and clear, very nice.

• Hand lume is original and clean. There are some tiny black pepper marks to the edges of the lume windows, but I can only see them with magnification
