Projects / Service: Fortis Automatic GMT 596.10.148 cal. ETA 2893-2
« Last post by kanikune on February 18, 2018, 09:40:46 PM »
This Fortis came to a service with minor damages. Lume was missing from the hour hand and cracked from the minute hand, GMT hand quick set was jamming and the spring bar was missing from the bracelet.


The "modern" ETA caliber is very familiar to others, big bearing for the rotor, especially.


As the caliber has GMT option, few wheels are added into the dial side. The GMT wheel sits on top of hour wheel and transmission wheel for these is also a clutch wheel. When GMT hand is advanced, the hand always advances in steps, because of the notches in the transmission wheel. Same quickset driving wheel drives both GMT and date quick set.


The small wheel just before quickset driving wheel was missing few teeth, causing quickset to jam.


Caliber in pieces.


And washed up.


Rest of the movement is very standard ETA. Keyless works..


New mainspring..


Barrel and 2nd wheel placed.


Barrel bridge getting assembled. The gear ratio makes hand wind almost undetectable.

Just google "ETA 251.262 pdf" and you'll find manual for this caliber. Other than that, you need to be more specific what you want to know about this. :)
