Leosweeneypod Wrote in reply to:Hi Leon, sorry for the delayed reply, All mechanical watches have a 'Break-In' period after service, the time taken for new components to bed-in and the oil to sufficently lubricate the areas of friction. This period is counted in hours rather than weeks or months. The maximum period being the time to fully wind and run-down the mainspring ensuring even lubrication. This 'Break-In' period is completly covered during the extensive testing and fine regulation carried out in the workshop after repair. We test the watches on machines that simulate movement to check accuracy and automatic winding efficiency but,as machines, they cannot replicate the particular conditions that each watch will be subjected to on return to its owner. It is these unique influences that may cause a watch to gain or loose immediately after repair. Over longer periods of time,(4 or more years after servicing), the oil starts to dry. This can cause either gaining or loosing depending on where in the movement dries first. Since your watch had been consistently loosing a minute for a long period and that has now changed, it may recently have received a shock or may have come too close to a magnetic field. Leo

Thanks Leo for the clear explanation.
I doubt it's magnetism given the faraday protection of the titanium case, not that I have been anywhere near a strong field.
Don't think its a shock as well as I haven't been particularly rough with it, besides normal everyday use.
It's still consistently slow... so I don't think it's that bad to be worried. At least for now...
Btw, with servicing, does the GST 3635 maintain the gold plated version of the 2892-A2 and all it's original parts? Or does it get replaced with the newer nickel plated version even with respect to specific movement parts? It'll be good to know...

Hi Leon, The nickel(Rhodium)-plated movements are not 'upgrades' from the gold-plated movements. All the components are identical except for the bridge/plate colour. The change was applied so that modern IWC movements should more closely reflect the finish and style of older calibres. A watch sold with either colour movement will always have that colour movement. Worn parts are replaced with identical new ones during service. I have never come across a 3536 with a rhodiumised movement but there may be some out there. Btw, although substantial, the titanium case of the 3536 is more susceptible to magnetism than a pilots watch, with a soft iron cage, as titanium is more transparent to magnetism and the sapphire crystal/brass dial offer no protection.

Interesting. It's great to be able to speak to a watch maker/repairer directly on this forum. Makes the IWC passion so much more personal. Thanks Leo.
