I bought a new Longines Conquest Automatic 39mm (L3.7188.8.131.52) last week which I am in love with... This watch has a Longines L619/888 caliber based on the ETA 2892-A2 movement.
However, I noticed today that the date changeover happens at 12:08am, whereas I expected this would happen at 12:00am. In fact, I noticed that the date changeover started at 11:45pm and then ‘clicked’ over at 12:08am.
Is this normal? This is my first automatic watch and I have only today learned that the date should only be set in certain circumstances. When I started wearing my watch I did not know this, and I am concerned that there is a possibility that I set the date during the ‘forbidden interval’. I’m not 100% certain that I did initially set the date during the ‘forbidden interval’ but it’s a possibility as I can’t remember. If I did do this, would this be a symptom of that? Is there anything else I should look out for that would also indicate that I may have changed the date during the forbidden interval?
Would really appreciate any help and advice. The watch is under warranty for two years and I bought it from an official Longines boutique.
Thank you so much! :)
