As Experts in Timewear, Swiss FineTiming specialise in watch battery replacement and can check your watch is waterproof at our Highland Park or Downtown – Chicago Boutique, whether or not they have been purchased from us. This process includes an inspection of the movement for cleaning and gaskets for replacement. The battery is then replaced and tested. To finalize the process, the watch is tested for water resistance. If any movement work is required we will contact you for approval with an estimate before any work is started. If you have any questions ask for Daniel P. Jordan, our Managing Director, at 1.312.337.4700.
