  1. Welp, whatever they gotta do to get those display casebacks to go down to 600m, they did it. With all the in-house movement craze going on they probably figured they need to show off their movements at any cost.
  2. That's a bit of a baseless assumption isn't it? Pretty much all Omegas these days with in-house movements including those with 300 and 600 meters water resistance come with display casebacks.
  3. End stones limit friction to a rounded point bearing on a flat surface, as opposed to a shoulder bearing against the perimeter of a pivot hole.
  4. I think that's an older generation brake. The clone would have very similar geometry but be made of metal.
  5. The shape of the balance is pretty much the only thing a pay attention to with these movements. It's either nickel or Glucydur and I don't think I've ever seen a Tag with a Glucydur 7750.
  6. Don't know about Zodiac specifically but I always thought it's so that manufacturers will have something to point to if someone somewhere loses an eye trying to open their barrels.
  7. I don't think this is true. I've read somewhere that ETA only offers 7750s at Elabore or above. If you are talking about decoration, it does not indicate at all what grade your movement is, as low grade movements can be delivered fully decorated just as well as top/chronometer can be delivered with basic finish. With regards to crown, have you considered going generic? Or maybe fitting a bigger tube and tapping new threads in the crown to fit? The rate can be adjusted via screws on the balance. Not as trivial to regulate compared to an index but is what most would consider to be a superior setup when it comes to achieving better rate stability.
  8. Yup. Afraid everything needs to come apart to access the barrel. Back AND front.
  9. Is proper tension applied to the seconds pinion? Did you oil it?
  10. I just press the tip of the hand down at the center of the 12 marker with a finger as I push on the plunger. With the hour and minute counters I just adjust the alignment by rotating the plunger as I'm pressing down. Also you might hear some people tell you to hold the reset button in as you install the hands. Does nothing here so save yourself the effort. It does press the hammer into the hour recorder but only the hour recorder, and when you let go of the reset and the brake comes to mesh with the teeth on the hour recorder wheel chances are the hand will be shifted out of alignment.
  11. Not strange at all considering it probably didn't get any oil from the factory.
  12. Sounds like stripped rather than crossthreaded. You can try sticking a needle or something in the same screw hole from the other side of the plate and apply pressure to the bottom of the screw as you unscrew. Genuine ETA's aren't immune to defects. I had one 7750 that came with hairspring that had like a 10 degree slant, and another one with a loose screw bushing for the chrono seconds brake. Both were brand new genuine ETA.
  13. I was watching a youtube video on the co axial escapment on Omega's channel. In it there's a snippet of the balance complete assembly process. It goes like this: stud is mounted in stud holder, balance with hairspring is seated in bridge, end of hairspring is slotted into stud, a heating element is brought to contact with stud, a flake of something is dropped into the slot, the something liquefies instantly. By the looks of it I would say they use shellac.
  14. Seiko movements definitely have the capability to perform in access of 300 degrees. I've gotten plenty to go above 300 by lubricating them like I would any Swiss movement, with the exception of using 9010 on the third wheel cap jewel.
