Build a custom GMT travel watch with a 24-hour bezel and an independent fourth hand for a second time zone. Timepiece Canvas draws the GMT hand and 24h scale and checks the combination — it will tell you if you add a GMT bezel without the hand, or vice-versa.
Open this GMT watch in the builder →A functional GMT maps to movements like the ETA 2893-2. Pair a blue sunburst dial, applied lumed markers and a jubilee bracelet, then export a parts list to build it.
What makes a watch a true GMT?
A dedicated 24-hour hand read against a 24h bezel or ring, powered by a GMT movement such as the ETA 2893-2.
Can I combine a GMT hand with chronograph subdials?
No stock caliber does both — Timepiece Canvas flags this so you don't design something that can't be built off the shelf.
