Rolex Perpetual Chronometer Reference 4134

Partially verified

This 1943 Rolex Perpetual Chronometer, reference 4134, is an automatic men's wristwatch housed in an 18K rose gold case measuring 37mm in diameter. The timepiece features the chronometer-rated Rolex Caliber 9 3/4 Perpetual movement, which utilizes a center oscillating weight for automatic winding. The case is characterized by teardrop lugs and an original rose gold nipple crown, and it is noted for being one of the few automatic Rolex models of its era designed with a snap-on case back. The watch is fitted with an aged pink dial featuring applied hour markers and a subsidiary seconds sub-dial. The watch is supplied on a vintage Rolex brown crocodile leather strap with an 18K rose gold Rolex tang buckle. Production of the reference 4134 occurred in limited quantities between 1942 and 1947, and this example has recently undergone service.

The snap-on case back is noted as a feature of the reference 4134, with the auction description stating that the back retains its original factory engravings in crisp condition.
