While I'm not sure Oscar Wilde was a watch aficionado, I still think he would take exception to your narrow view on the worth of certain watches (for obvious reasons).I think I am poor by the forum standards then.
There is no point in spending 400 bucks for servicing when the watch is not at least 10K in cost. Now I understand the success of Timex.
Timekeeping is not a reliable indicator of the need for service - I define the need for service as when the lubrication has failed and parts are now wearing out.My question is, how can you tell when a problem appears with, say, a three handed watch. Just if it starts losing/gaining a significant amount of time? Or something more serious?
Do "innovations" such as argon gas filled watchcases and copper sulfate drying capsules affect the service interval.
Certainly with a more complex movement there's more opportunity for something to go wrong, and that may require attention where a simpler watch may not. But from a pure service interval standpoint, the answer is no.Do you find that watches with complications (i.e. chronographs) require service more frequently? Even if modem calibers.
Slightly off-topic, but does Sinn provide you with access to parts, etc., as an independent watch maker? For example, if you needed a new crystal could you get one? Or is it just that since they use standard ETA movements, etc., you have access to the parts you need for the movement but not any Sinn-specific parts? I have a ~12 year old 856 which I am thinking about sending in for service soon(ish)...The short answer is no. I am a Sinn fan and have owned one, and serviced many.
