Glycine watches require careful treatment together with a full service every three to five years because there is always a certain amount of abrasion in mechanical devices. Our full service is a thorough and time-consuming process that involves completely dismantling, cleaning, lubricating, and reassembling the movement. After servicing, every movement goes through a special series of tests, where it has to conform to stringent precision standards. This is the best way to ensure that your Glycine watch will continue to run accurately for years to come. The work comes with a one-year guarantee.
