From 1968 until 1970 the Fontainebleau was a series of unique automatic watches of Hamilton. Most of the Fontainebleau line were big chunky watches like the one you see here. It has a Brevet waterproof case, sealed with a ring that holds the caseback.
This reference 64047-3 has a dark blue dial, a date window at six and is powered by the Hamilton 64A automatic movement (based on ETA 2542). The diameter of the watch measures 41mm but due to the thickness of only 11mm the watch wears small.

This Hamilton case opener set is used to fixate the casefront to be able to unscrew the ring at the caseback in order to lift the caseback and get acces to the movement.
Here you see the different Fontainebleau reference numbers this set is meant for.
The Hamilton Fontainebleau Chrono-Matic
The most famous and sought after Hamilton Fontainebleau is undoubtedly the Hamilton Fontainebleau Chrono-Matic. This iconic automatic chronograph watch had not only the remarkable form but more important was powered by the Chrono-Matic calibre.
One of world's first automatic chronograph was presented to the world in 1969 and was the product of a joint-venture of some of the then leading Swiss watch factories Hamilton-Buren, Heuer-Leonidas, Breitling and Dubois-Dépraz.
Definitely a grail watch when it comes to the Fontainebleau series of Hamilton and iconic 70's chronographs in general. Perhaps some day one will find it's way to me.
