If you've got a watch - a REAL watch - at some point it's going to need repair; in Toronto - this is the place to take it. If you just need a battery replaced in a "designer" watch he can certainly do that as well - unlike the denizens of the malls and retail jewelers, he can actually repair complex winders and autowinders. Vintage, Modern, obscure - he has not failed me yet. Not so much a shop as a cubby hole, your fine mechanical timepiece will be evaluated and you will receive a prompt, reasonable estimate for repair. You know that broken watch given to you by your father/grandfather/celebrity impersonator that's been sitting in your drawer? The one deemed "un-fixable" by your local jeweler? He can fix that too.
This man is a genuine watchmaker and there aren't that many left.
