The Fortress GMT

This is the latest (and in my opinion, greatest) iteration of Graham's Fortress collection!

The Fortress GMT is an ingenious solution to an occasionally frustrating problem, adjusting the second time zone on your GMT watch.

The typical mechanical GMT watch operates with a "position" adjustment from the crown, meaning you have to first remove the watch, unscrew the crown, do the math (usually not too complicated, but still an opportunity for a miscalculation), screw the crown back down, and hopefully have the correct time for the correct time zone. I don't mean to be overly dramatic, but I have encountered more than one colleague from the Fourth and Fifth Estates who have been off by an hour (or two) and missed appointments, etc., owing to an incorrectly set GMT hand.

Enter the Graham Fortress GMT! You will notice a small button at the tip of the crown. This button engages the GMT hand with a push. Arrived in a new timezone and need to set the second time zone? Not a problem. Simply press the GMT button on the crown to advance the hour hand by one hour. 

It's available in black, blue, green and a rather saucy two-tone blue and brown dial (which is limited to 100 pieces).  Fairly priced at $5,750.00 and available direct from Graham on their online store - https://graham1695.com/collections/all
