百达翡丽，18K金自动上弦万年历链带腕表，配闰年及月相显示，型号3945/1， 约1991年制，附原厂证书、额外底盖、盒子及外包装

The Patek Philippe reference 3945 was introduced as a variant of the celebrated Ref. 3940, the noticeable difference between the two was that the former was offered exclusively with an integrated gold bracelet. The Ref. 3940 had lugs that accommodated a detachable leather strap.

Produced between 1985 and 1998, this timepiece finds a place amidst the most elegant perpetual calendar timepieces ever made by the brand. Reference 3945/1 was, like it’s sister reference 3940, produced in two distinct main series, distinguished by the leap year display: the first series with sunken leap year dial without “cross”, the second series showing a crossed leap year such as the present watch.
