2005SUBMARINER Posted November 18, 2006 Report Posted November 18, 2006 hey guys just bought a cool looking pam 090 & it comes with this type of asian movement asian movement does any one knows the proper method of regulating this type of movement ? i dont think it comes with the eta style + - to regulate .. thanx ... p.s. i think its a copy of eta's 2894 movement ..
RWG Technical Posted November 18, 2006 Report Posted November 18, 2006 Look at the balance wheel and hairspring with your loupe...note the arm that the hairspring is attached to - that's the stud arm, you don't want to move it. Look at the other arm, it's got the hairspring running through it and two small arms that stick out from the bottom, this is the regulator arm, towards the stud is slower running, towards the other way is faster running... It looks as if the arm with the blue dot is the stud arm. RG
2005SUBMARINER Posted November 18, 2006 Author Report Posted November 18, 2006 thank you very much sir The Zigmeister ! dont know why the makers of this movement didnt use the same method as the eta regulating device its a breeze to regulate with the > + - screw thing on the othet hand this asian movement will be hit or miss with that type of regulating device
2005SUBMARINER Posted November 18, 2006 Author Report Posted November 18, 2006 The Zigmeister does this movement have a name ? is it a 7750 asia movement without the chronos ? or just asian 21j like the ones you find in the standard asian submariner? thanx for your help .
2005SUBMARINER Posted November 19, 2006 Author Report Posted November 19, 2006 That movement is a Sea-Gull ST25. THANK YOU SIR !
Rikske Posted November 19, 2006 Report Posted November 19, 2006 Have this same movement in my PAM090 Power reserve. Regulated it but it is very difficult to dose the amount of movement of the regulating arm. It is more trial and error till you get it ok. The etachron with its fineregulator screw on the otherhand is a joy to regulate. Good luck , i think i opened my watch a dozen times before it was running quite accurately now.
