I love yours and want a Ref. 4838 or 4907 with center seconds Cal. 1008/BS to add to my CR collection.
It looks like time for a Chronometre Royale roll call? Here is my contribution:
Ref. 6110 with Cal. 1007/BS from 1955. The first year these qtr. maltese lugs were used. Used to celebrate VC's 200th anniversary, these lugs were used on several models in 1955 and they became very popular. These watches with Cal 1007/BS and Cal. 1008/BS were the first wristwatch versions of the CR, and the /BS stancds for "Balancier Stop"...these were some of the first movements that had a hacking seconds function for civilian use.
Ref. 6694, aka "Batman's watch". This one is from 1971 and uses Cal. 1072/1, which happens to be the first automatic movement used in the CR family. My only watch with a diamond, but I am attracted to the Patrimony with diamond hour marker indices.
And last, but definitely not least, the Grandaddy of CRs. A 1908 pocket watch CR. VC trademarked the name “Chronometer Royale” in October 1907, so this is one of the earlier pieces made. Its still running today as accurately as any of my other watches.
Your automatic has very elegant diamond on dial.
