Good people of RWG, I have recently been told that the movement in my IWC Top Gun (Asian Valjoux 7750) is knackered and needs replacing. Problems began when the watch stopped (for no reason) while on the watch winder; to overcome this I started manually handwinding the movement … This worked OK for a few weeks, until one day (whilst hand winding) the noise and feeling inside (sorry for lack of technical terminology) went from a pleasant smooth feel, to a nasty internal ‘crunching’. At this point it was game over … into the repairers, where I was handed the bad news. The joys of rep ownership eh? Boo!
So, I’ve bitten the bullet, and decided to go ahead with a brand new movement, fully serviced and pressure tested. What I now need to know is when the watch is returned to me, how I can prevent a similar situation occurring in the future?
I have heard all sorts of stuff & frankly, I don’t know what to believe (e.g. don’t change the day / date between the hours of 10-2; avoid sudden ‘jerky’ wrist movements (ha, ha!); don’t use the chrono function (which seems weird to me, as surely that’s one of the joys of chrono ownership!) etc etc.)
In short, (and I have read previous posts on the subject) … What’s the score when it comes to 7750’s? Should they be handled like spider webs or are they as robust as regular (non chrono movements)? Lets set the record straight once and for all. Look forward to hearing your comments and as always, many thanks in advance. rclough
