Hello Gentleman, Anyone ever work on this watch before? I've been enjoying this hobby for a while now and have had some decent results. Am progressing nicely to more and more complicated movements, but man, for the life of me, I can not figure out how to remove this ETA 7750 from the ring around it. I've successfully removed the movement and its holder from its outer carbon fiber case, but cannot remove it further. I've removed both pushers and the stem and it, frustratingly, doesn't simply drop out when inverted. It also doesn't rotate from side to side within the outer movement holder.. it is stuck fast. I'm a little embarrassed honestly. The red arrow points to a line in the movement holder, but it is seemingly one piece and not separable there. I guess they just needed to reduce some outer diameter there. The ends of the minute and chronograph hand extend over the minute marking ring so would that mean that that minute marking ring is part of the dial attached to the movement? I guess I'm asking where does the dial end? Any point in the right direction would be most welcome. I've never worked on this movement before and I am chomping at the bit to do so. It represents the next challenge in my progression. But obviously cant start until I remove it safely and I'm stumped! -

Donor movement received. Now waiting for a proper & calm time slot to perform the transplant. -

Hi Joe, I mean the situation when the escapement can be unlocked when pallet fork is pressed as the guard pin to touch the guard roller. This will be possible if the guard pin is short or the depthing of the escapement is not deep enough. The pallet fork was replaced, but I don't think it was adjusted to work correctly with this movement. Of course, if there is defect on the guard roller, it also can lead to such problem. -
Hi everyone, I am new to watch repair and loving the whole process, even some of my fails…maybe. Right now I am looking at purchasing a press for fitting watch crystals, and I was wondering if any of you have had experience with the BMC model (seen in photo) and if you know whether the Robur press dies would fit, or, if not, what alternative dies might as I am having trouble sourcing original ones. I know that the subject of crystal presses has been a well covered topic here, so I apologies for bringing it up again but I hadn’t found any past threads on this points. Any help on this would extremely helpful. Thanks! Joshua -

Hi, I just wanted to share the unmistakable quality of a Rolex made in approx. 1990. Cleaned and serviced for a friend using appropriate oils and greases, with Epilame on the parts recommended by Rolex. New mainspring and upper setting and jewel for the minute Pinion (cracked jewel). Run in overnight and then worn on the wrist for a couple of hours to warm. Without any adjustment to the balance weights the watch ran at 0 SPD DU, all positions within +3 and -2. Vertical amplitude after 24 hours of 230 degrees minimum. Watch running at zero seconds per day on wrist when worn 24 hours. Serviced just once before 20 years ago. No need to buy the Microstella regulator tool, not this time anyway 🙂 No scratches or damage caused to screw heads and bridges. All seals replaced and waterproof tested to 60 metres. All good practice for when the time comes to service my own Grand Seiko.
