Preferred AD-based watchmaker, Chicago area?

[Poodlopogus]

Need to have a warranty repair done on a 32xx and, based on my other thread (confirming my instinct of going local), any experiences with the watchmakers in the Chicago area authorized to do warranty work?

Looks like there are about 5-6 of them within ~100mi but not sure if some are better than others?

Don't have a relationship with any as far as purchasing watches, and that would be secondary anyhow as this is warranty work and all I care about is the skill of the watchmaker.

The Nigerian guy at CD Peacock in Oak Brook is highly skilled. Best of the best.

Is this the same warranty work because your watch is running 4 seconds slow ?.

Dont worry over a few seconds in 24 hours, the escapement of a mechanical watch pushes the gears 432,000 times a day, so even a watch that runs -4 seconds is very high precision, given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, mainspring power reserve,temperature variations, subtle changes in lubrication and friction, shocks, and so on.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no.And if any mechanical watch performs consistently inside the COSC spec of -4+6 seconds a day don't think anyone could ask anymore from any purely mechanical watch

And any modern day wristwatch chronometers are, by the almost 300 year old 18th century navigational standards imposed on John Harrison,H4 watch,quite laughably inaccurate even by todays standards.How about just 5 seconds slow after 63 days at sea,in one of the toughest environments known to man, not bad for a almost 300 year old watch.Now in those days no modern machinery no computer designs no robots,just his bare hands and crude tools.So next time when you look at your watch and only a few seconds out it wont feel so bad.Your watch is fine just wear it and enjoy it whats in a few seconds a day.

You’d want to use RSC no?

Your point is very well taken. In reality, the -4, in and of itself, would be no cause for concern. However, what I experienced was a watch that went from being very, very consistently +1(ish) to all of a sudden around -4(ish).

Amplitude, in and of itself, is also irrelevant to me. In fact, I think it's great if a watch can maintain accuracy despite dropping amplitude. But, if amplitude drop (which may or may not be the case here) combined with time loss indicates some other issue, I'd want to have it looked at. I recall reading some posts here from a watchmaker who said there are now some parts he routinely replaces when a watch comes in exhibiting these characteristics.

All that is to say, this is a question of ensuring reliability, not the four seconds per day.

I'm talking about the AD-based workshops that do work as a "satellite" RSC. When looking up service centers on the website, it lists five IL ADs as also being service centers (along with two in Milwaukee and one in IN that are within about 90min).

Apparently, they are allowed to do any/all warranty work for most models (depending on watchmaker's qualification level) aside from perhaps those requiring special pressure testing equipment.

Had service done at Razny Jewelers ( in-house watchmaker ) in Addison recently. Completely satisfied with work done.
