A fine and rare 18K white gold Longines Reference 6900-4 dating to the 1960s with incredibly slim case design (5mm thick), extremely elegant and classic dial design with simple, long baton hour markers and pencil hands.

The Longines logo simply printed and floating against the simple curvature of the case is a exercise in restraint.

The Frederic Piguet caliber 310 is in excellent running condition, recently serviced and ready to wear.

Paired on a sand leather calf grain.

It is unusual to find these in 18k White gold. 

Interesting fact: This was Longines competition for the slimmest dresswatch competing with Piaget at that time. The cal 9P at 2mm, the caliber 310 (FP.21) in this Longines was 1,73mm.
