ETA’s 2893-2 is a modular GMT movement with central seconds and date. It is derived from the similar ETA 2892A2 and is part of the third-generation ETA 2890 family. Cal. 2893-2 appeared in 2002 alongside the similar ETA 2893-1 and ETA 2893-3 and remains in production today. The main difference between the three is as follows:
- ETA 2893-1: 24 hour central disc, date
- ETA 2893-2: 24 hour central hand, date
- ETA 2893-3: 24 hour central disc
The GMT feature and date wheel are adjusted with the crown in position 1. Turning it clockwise advances the GMT hour hand in 1 hour increments, while turning it counter-clockwise advances the date wheel.
The IWC 30710 is a refinished ETA 2893-2, as is TAG Heuer Calibre 7 GMT.Images are taken from official publications and are used here for commentary and educational purposes. Copyright is held by the original owner as noted.
