1977 Rolex GMT-Master (Ref. 1675) Mk. III Radial Dial "Blueberry"

The elusive and rare “Blueberry” GMT-Master is essentially just a regular reference 1675 from the 1970s that was originally fitted with an all-blue bezel insert.  Blueberry GMT's are most commonly fitted with the GMT Mk. 3 dial variant referred to as a "radial" dial due to the smaller sized lume plots. Unlike the other colors of bezel inserts that have been available for the GMT-Master line of watches, the all-blue insert of the “Blueberry” GMT is not something that Rolex ever officially offered as an option at any of their regular authorized dealers. The entirely blue, GMT bezel insert was manufactured in small numbers primarily for the Eastern market during the 1970s, and reserved exclusively for special orders by select retailers and military groups. Some examples can be found with the UAE Air Force emblem on the dial. 

This specific example of the Mk.3 "Radial or Mini" dial would make a great daily driver for the man always on the go and would make a great addition to an existing collection as this specific dial variant of Ref. 1675 GMT's are becoming harder to find due to the fact they are becoming highly collectible and sought after among collectors.

The case has been previously lightly polished but retains thick and even lugs. The "blueberry" insert, correct with "ghost triangle," remains in excellent condition showing very light wear with no signs of fading. The Oyster 71360 bracelet with 580 end pieces retains 11 links and remains in excellent condition showing minimal stretch with light wear.


The mark III "radial dial" remains in excellent vintage condition, the dial has achieved a very light natural texture that is consistent throughout and is only visible under loupe. The original tritium lume plots have taken on a charming ivory patina and shows no degradation under U.V. light inspection. The original hands have aged slightly darker than the lume but match the overall look and feel of the watch, under U.V. light inspection the hour and sweep-seconds hands remain fully intact, the minute and GMT hands exhibit very minor cracking. The metallic date wheel is era correct with open 6's and 9's.


None. The watch was just inspected by our watchmaker and is keeping time at spec, previous service history is unknown.
