Rolex GMT-Master Reference 1675 with Gilt Dial

Partially verified

This Rolex GMT-Master reference 1675 is a vintage mechanical wristwatch, identified by a serial number corresponding to 1965. It features a 40mm stainless steel case and a black 'Gilt' dial, characterized by gold-colored text produced by the underlying brass plate showing through the black finish. The watch is equipped with a rotating bezel featuring a 'fat font' insert that has faded to blue and peach tones. It is mounted on a Jubilee bracelet, reference 6251, with 55 end links and a clasp stamped '4 60'. Internally, it houses an automatic mechanical movement, which the source reports has been fully serviced. This specific example retains its mirror-like dial finish, although the source notes minor wear near the 6, 11, and 12 o'clock positions.

Object description

Case and Dial

The stainless steel case measures 40mm in diameter and maintains a polished profile. The watch features a black 'Gilt' dial, a design element where the gold text is revealed by the underlying brass plate visible through the black glossy coating, creating a reflective surface. The source notes that the dial maintains its mirror-like quality despite reported minor defects and wear located at the 11, 12, and 6 o'clock positions.

The rotating bezel is fitted with a 'fat font' insert that has undergone discoloration over time, transitioning into muted blue and pale peach shades.

  • “این نمونه به صفحه مشکی براق از نوع موسوم به Gilt مجهز است”

  • “قاب چرخان ساعت دارای اینسرت با فونت درشت (fat font) است که گذر زمان رنگ آن را تغییر داده”

Movement and Mechanics

The watch operates on an automatic mechanical movement housed within the stainless steel case, which is sealed by a screw-down case back. The movement has reportedly undergone a full technical service by the source's horologist.

While the movement's full performance history is not detailed, the watch is classified as a GMT-Master, a functional series originally developed in the mid-1950s to assist airline pilots in monitoring two time zones simultaneously.

Bracelet and Provenance

The watch is presented on a stainless steel Jubilee bracelet identified by reference 6251. It is fitted with end links marked reference 55. The bracelet clasp bears the specific hallmark '4 60', which aligns with the production timeframe of the watch case.
