RAF 1976 6BB "Lost Navigator" by Precista

One of the rarest RAF watches out there. Very similar (seemingly made to the same spec) as the contemporary Hamilton and CWC W10, this were until recently something of a mystery. This calibre was both much smaller in number - only 2000 were ordered on a single contract - but also completely sterile. Thanks to some great work from my friends over at Waecce Watches, it was recently discovered to be made by Precista, a brand owned by Southern Watch & Clock Supplies Ltd, that supplied divers, chronographs and field watches to the British military during the 70s and 80s. This example is in wonderful shape, and is a very low serial number, 30 of 2000, the lowest number I can find!

Condition

Excellent used condition. Dials, hands, etc are excellent bar a very thin area of wear to the very edge around the 6 marker - its almost impossible to see/photograph. Some light scratching and wear to the case and crystal. The movement is keeping great time, it's literally to the second over 6 hours with a power reserve of approx 20 hours.

Size

• 35mm side to side (excluding crown)
• 41mm lug to lug
