Just share with you this great watch .. my M1. Was on my wrist for the past 4 years. Still one of my favorite.
The Lemania 5100 is robust ..... still tick and accurate.
Small problem with the watch crown that it won't lock but works fine. I am reluctant to send
I state UK only, but will ship anywhere so long as you are OK about international shipping insurance and its limitations (500 EUR/GBP I believe)
