Can anyone recommend a basic watch adjustment/repair kit? I'm looking for something that will allow me to resize bracelets on Rolex, Omega and Breitling reps. I would also like to be able to remove the case backs to check out the movements. Eventually I'll start practicing on modding my $50 genuine seiko before I get the skill and experience to start modding my reps.
Is there a kit that contains everything I'll need (I think I'll need a separate Rolex case back tool - what about for the Omega and Breitling case backs?)
What is the consensus on paying $50 or so extra for 'waterproof' service on a rep costing over $250? I've seen some replicas state that they are water resistant to certain depths while others just say water resistant. Assuming that I won't be diving in the watch, is this service worth it or when a rep says 'water resistant' would that cover activities such as swimming, showering or hand washing?
