El Primero accuracy - what's reasonable?

[Bonefish Blues]

After a recent service my EP Zenith has settled down to a pretty consistent 7secs a day gain. When new (c8 years ago) it was accurate to within a very few seconds a month.

As it was done by LVMH as part of a repair, I do have the ability to send it back for re-regulating within the one year warranty period.

My question is, is it worth it, i.e. could they improve its accuracy to finer tolerances?

[Bonefish Blues]

Thanks both - on balance I'll probably leave it and see if anything changes over the coming months.

Grrrr - the lower push button has fallen off again (3rd time).

Any mileage with LVMH Service Dept do you think, given they last "fixed it" less than 12 months ago, albeit we're now outside their 1 year post service guarantee period.

Duval dont have an enviable reputation. Id try soemwhere a little better, like Steve Burrage at Ryte Time.

I haven't been impressed TBH, but don't really fancy paying for something they haven't done properly again.

Thought I'd drop back onto my old EP thread to ask another question.

The lower pusher pinged off again. No problem really, but this time I couldn't find the tiny return spring that sits underneath. I've just had a quote to replace it: £126... Reason? It only comes as a unit with both the pusher and the spring.

Any idea whether the spring is a generic item that I might be able to pick up elsewhere or do I have to bite the bullet and buy and what might just be, pro rata, the world's most expensive spring?

If this was my watch, Id now be sending it to Joe Horner at Anglesey Clock and Watch. I suspect that all independents might struggle to obtain the parts though.

I agree - cartels R us makes this an issue, which is why I was wondering if the spring is unique to El Ps or a bought-in item, in which case there's a chance?
