I own two R Mille's 05 and 14,I had to send the 05 back last year for routine sevice. wear it every day in south florida hot and sticky, ocean and pool even tennis with the new strap holding up very well no problems and also great accuracy.RM 14 is just a beast in every sense of the word runs well no issues going on 18 months.
Over the years I have owned numerous watches,I had to send a patek back twice in one year had a problem with roger dubuis,IWC,AP and F .P journe with three different watches, Thease things happen.
My RM may stop working tomorrow who knows but one thing I do know the next watch I buy will be a RICHARD MILLE.
Good luck.
