Notes

Dial, case and movement signed. DIM. 42 x 44 mm. THICKNESS 7.5 mm. Approx. overall length 155 mm. Known today as the JUMBO due to its impressive proportions and later smaller sibling (Ref. 3800), the original, first generation, 3700/1, manufactured from 1976, was replaced by the 3700/11 with narrower bracelet (*16.5 mm.WIDTH reduced to 14 mm) after circa 1982. *Patek Philippe Steel Watches by John Goldberger Page 363 With a retail price, in steel, in 1978 of USD 3'100 and was labeled as the world's most exclusive steel watch. The current example is in excellent overall condition with nice definition to the bezel, a sharp case, a close to mint dial and still with a Patek Philippe service tag on the caseback (although the date of the service is unknown).
