The Rolex GMT appears to have emerged from a long term lull as one of the most under valued Sports models on the market for so long. Market prices have been climbing lately driven by collectors looking for original examples.

This model is fitted with the original Tritium dial with gently toned luminous, which collectors now call the "custard dial". The dial and tritium hands all have matching tone and colour. Inspection of the 24 hr hand under a loupe reveals that this luminous must have been replaced at some point but it was sometime ago as the material is still tritium.

The serial number in the 5 million range suggests a production date of 1978 and the date code on the inside of the caseback confirms the production.

While the case is in generally excellent condition with fat lugs and sharp edges, please note the slight angle on one crown guard shoulder.

The Rolex calibre 1575 movement was recently serviced by my Rolex trained watchmaker and is keeping Chronometer grade time.

The original Rolex Oyster bracelet, reference 78360 is still fitted to the case.

Overall this is the nicest vintage dial on a vintage Rolex GMT 1675 that you are likely to find in the marketplace today.

The case measures 40 mm wide by 48 mm long.
