Navitimer 806 dating
The reference 5514 is a very special Submariner, as it was only delivered to the COMEX, the logo you see on the dial here.Founded in 1961, COMEX (Compagnie Maritime d’Expertises in French) needed a watch for its deep diving activities, and Rolex immediately considered its Submariner.Indeed, any replacement of the dial or hands would have had a steep impact on the originality of the watch, and thus its value.The Breitling Navitimer was launched in the early 1950s with only one customer in mind: pilots, hence the collaboration with the AOPA (Aircraft Owners & Pilots Association), which distributed most of the early examples to its members.As a result, rarer vintage watches are heavily in demand and extremely collectible and like any high end vintage item, retain their value well if correctly looked after.

The power reserve indicator came in two different shapes: a regular sub-register for the present reference E501 and the "porthole" for the reference E502.
This innovative watch could not be wound manually (the hidden crown only allows for time-setting), so its movement was designed to keep enough energy to instantly re-start whenever worn, hence the red zone found on this indicator.
Why not shake the watch when the power reserve is entirely down and call it a day?
