ETA 7750: Part 3 - Reassembly: Escapement Lubrication, Chrono Bridge, Automatic Bridge, Motion Work

[@bangy55]

Thank you so much, Stuart. You take the fear and trepidation out of my first 7750 service. Please don't get discouraged, it takes quite a while to develop a following. I for one can imagine all the work that went into this video project. You are a gifted teacher and narrator. Thank you for sharing.

This was so helpful, thanks for such a detailed assembly and demonstration. I'm in the middle of a teardown of a Fortis with a modified 7750 GMT, which is really interesting -- it was modified to remove the day feature, move the date to 4:30, and add a 4th subregister at 3:00 with a small 24hr hand. The 2nd crown position quicksets the date, but also can jump the main hour hand backwards 1 hr at a time, without affecting the 24hr hand, so it's like a real "flyer" GMT unlike the usual ETA/Sellita versions that just jump the GMT hand. The date even moves backward with the jumping main hour! It's clearly a Fortis mod, they didn't even replate over where they drilled out new recesses in the calendar bridge for the modified work. Super unusual!

Hey Stuart thanks for the interesting video. I was quite amazed by the way you oil the escapement. We were thought to oil the face of the exit palet stone for about half or two thirds, and repeat every five teeth of the escape wheel. That makes it rather difficult to get it right every time. So I immediately tried it your way and boy what an improvement and a consistency like no other. Thanks for the lesson and I could kick myself for not coming up with this method myself ;-)

What grade of movement is this 7750?

Thanks for this video series about the 7750, great job and so well explained. I havn't serviced a chrono yet, but maybe one day.. Will there be a fourth part to show the remaining of the watch?

Awesome job brother! I'm about to change the dial on my Chronomat (7750) for the first time and I am wondering, can the seconds hand become out of sync somehow if I don't put it back exactly where I lifted it off? I figured I would hack it, release the stem, take out the movement, change the dial and then just put the hands back on exactly as they were before I changed the dial or do a reset by going to midnight then just pop the stem back in, sounds okay? Any tips? Very nervous about this. Have a good day!

Thank you for the excellent video. I have a question, if I may ask. I have a Breitling chronomat which has only the date window (numeric) but not the DAY of the week. Surfing the web, I see no reference to this configuration or variant of the 7750. Does that mean that it is the same movement as the date AND day where the day crown is simply removed? In other words, if I can find a 7750 with both date and day, will it fit in or will I have to annihilate the day feature by some procedure? Thank you if you can answer this concern of mine. Best regards.

Hello, it's very good what you do with your videos, people discover a little about the watchmaking profession, there are 2-3 things that you can correct, I'll give you a little example (your kitten on the counter cast pivot). On the other hand, you will let me know if you can understand me with the translation.
