- A FINE AND VERY RARE LARGE STAINLESS STEEL AUTOMATIC CUSHION-FORM WRISTWATCH WITH DATE AND BRACELET
REF 3700/1 MVT 1305041 CASE PROTOTYPE 'JUMBO' NAUTILUS MADE IN 1978
- stainless steel
Reference 3700/1 was equipped with calibre 28-255 C based on a LeCoultre ebauche, a really thin automatic movement for that time. The cases were manufactured by Favre-Perret and were 120m waterproofed. The dials were hand made by Stern Freres. In 1980 Patek Philippe started to create cases and bracelets in their Ateliers Réunis workshops and the Nautilus changed its reference number to the new 3700-11.
For a description of a reference 3700/1 in stainless steel and the caliber 28-255, see: "Patek Philippe Wristwatches" by Martin Huber & Alan Banbery, 1998 edition, pages 230-231.
Please note that both dials were marked with the same stern freres numbers on the back: 93Y * 210TT which means that the black and the white dial are prototype and was made before 1981.
