洗油找邊間好

上次返廠洗, 2年半隻 PAM90 , 而家又上唔到鍊, 重要平時大力轉個陀,會震動有一下吱吱上鍊聲, 比佢洗完油冇咗果下聲, 同佢地講又話係咁,隻錶又上到鍊又用到, 吹佢唔脹

PAM090 is using the neutered VJ7750, it's a chronograph movement with the chronograph removed.

The buzz or whobby you hear/feed is because the movement has a unidirectional winding mechanism, when it's being swing in the non-working direction, it will free spin and causing it to whobble.  It's a strange feeling at first but it's all the same for all 7750 movement.

7750 auto winding mech usually is quite reliable as long as all the serviceable parts are replaced and oil properly.
