Grande Date

In memory of the first calendar watch the House of Du Bois & Fils presents a crowning achievement of watchmaking artistry in a case of precious gold: Chronograph with Big Date and Annual Calendar

Mechanical large-date display in separate windows on the dial. The 1st display window shows the tens, the 2nd display window the digits

The calendar feature takes account of the various lengths of the months, of 30 or 31 days, throughout the year. It therefore needs correcting only once a year, at the end of February

A rare chronograph movement made by Dubois-Dépraz, Cal.4900

Sapphire crystal, sapphire transparent watch back

Limited edition of 300 watches only

Massive 18 carat gold (750) case, in yellow or white gold

In association with the one year calendar, this large-date display is very comfortable

The watch is waterproof to 30m / 3 atm
