Definitely not the case in the city, in my experience. Most jewelers sell diamond and gold jewelry, rather than watches, and the ordinary ones that sell watches seem to have no idea about anything beyond battery changes.
There are some watchmakers here, though, but the majority outside of the battery replacement specialists seem to cater to high-end watches. I'd just like to do water testing on some Seikos I've modded and don't want to pay $50+ for it.
If anyone here has had experience with some trustworthy affordable shops, please let us know. Have a feeling there has to be some small place in the Diamond District or another neighborhood that won't charge two arms and two legs. Thanks.
