European Watch & Clock Co, was the partnership between Cartier & Le Coultre who built watches & clocks exclusively for Cartier; the cases were made by Cartier & the movements & dials by JLC.
Two piece case with integral bezel, snap back, downturned lugs and domed bezel; the inner caseback bears the manufacturer’s name and the hand stamped case number 36231. The date can be adjusted via a pusher at the 8 position. The case itself was made in Paris by Cartier and bears French 18k hallmarks both on the case body and back. Like all Cartier watches of the period, it does not use springbars, rather the solid gold bars are screwed in, as with modern Cartier and Panerai watches.
The movement is not numbered and is gilt finished, with “cotes de Geneve” decoration. 15 jewels, lever escapement, monometallic balance with adjusting screws & self compensating Breguet balance spring, ‘stick’ regulation, adjusted to 3 positions. The movement is essentially a JLC calibre 410 with the addition of the two calendar complications.
The gloss black dial has the date printed in red on its extreme periphery, just outside the ‘railway track’ minute track, the hour indices are bright white printed Arabics, the aperture for the day of the week is just below the 12, there is a sunken subsidiary seconds dial at 6 and the dial is signed Cartier just below the 12 and ‘Swiss’ at the very bottom.
The case is in 85% condition and the dial is 90%, whilst the movement is 95+%.
The watch measures 29.5mm diameter, 36.5mm lug to lug and 9.5mm high, it takes a 17mm strap and a black crocodile strap is fitted with an 18k deployant buckle.
