Many people ask me if watch winders are required for every automatic watch - following is my advice:1) Basic Watch, no complications except date - RARELY WORN
No need for a watch winder to keep it running, just "quick set" the date when required2) Basic watch, no complications except date - WORN DAILY EXCEPT WEEKENDS
In this case, if your watch wont cover the 48-72 hour weekend break, then a watch winder saves unscrewing the crown and resetting it each Monday morning3) Watch with multiple complications like Full Perpetual Calendar.
A MUST for a watch winder - trying to reset a timepiece with full "perpetual calendar" is a "true" nightmare in disguise full of hidden potential very damaging results.
While helping in GOLDRUSH (Spain) I sold a colleague a Vacheron Constantin skeleton Full Perpetual Calendar an amazing piece of HOROLOGY, but I INSISTED he bought a watch winder or I would not sell him this piece. Why? This outstanding dress watch, was not a daily wearer BUT a piece of Haute Horologerie and trying to reset the dates every few weeks/months would border on a nightmare.
He must have a watch winder.
After research he bought from BARRINGTON.
This was his testimony to me" I've had a company that have been very good to me called 'Barrington Watch Winders' based in U.K the product quality and customer care has been second to none."
