GMT 3 Diver Big Crown

The GMT diver has a storied past. It was never planned to be part of the diver range. When the original diver’s range was conceived, it featured the CAL2533 movement with linear power reserve, 24hr hand and sub second at 9H. Many customers had lamented the fact that we did not have a GMT version of the diver at that time so we obliged and hence the GMT diver was created.

The original GMT Diver had the date corrector pusher on the case and crown guards like the rest of the diver range. It also featured a white date window as the movement used was unmodified. The GMT Diver is now in it’s third iteration. Gone are the crown guards and in it’s place is a large winding crown. The sandwich dial has also given way to an applied indices diving watch dial and a black date disc. The 24Hr/ GMT rehaut have larger numbers to increase legibility.

Much like the AG Diver Big Crown, the following enhancements were also done; re-drilled lug screw holes so screws are flush with the lugs, refinished cases (brushed), stronger hand applied lume pip, hand applied C3 Superluminova on dial, black date discs to match dials, stronger ratcheting action on the bezel and an overall more accurately tuned movement. Only 45 hand made pieces have been made.
The bezel design features a CNC machined grip that mirrors the bezel sides. This design increases the functionality of the crown as it is easier to grip. The bezel  is intentionally designed to be 6mm high for ease of handling.  The additional height also gives the illusion of depth to the dial creating a ‘pothole’ effect, making the watch appear more three dimensional. This effect is further enhanced by the applied indices which stand proud of the dial giving it an additional depth. The swooping down lugs are also designed to hug the wrist better and make for a much better fitting watch for smaller wrists.

The usual dive watch specs are still covered, 120 click anti-clockwise unidirectional rotating bezel, C3 lume on hands and dial, anti-shock protection and large lume pip. Our dive watches have been tested to much greater depths due to double seals on ALL openings and includes a screw down crown.

Included with the watch and matching brushed bracelet is an additional strap. Please specify between rubber/ leather and the colour (chose from our strap). As shown in the pictures, we recommend a black rubber #02 strap with a Flush Type #02 buckle. Note that additional strap comes with a tang buckle and if you decide on the deployant buckle it is an additional charge as listed below.

The GMT3 Diver Big Crown illustrates how at moVas we are rarely satisfied with our designs and continually seek to improve them even if they are small and appear to be insignificant to most.
