Hello All
There seems to consistant tone of negativity by several forum members regarding RM and reliability.
Let me allow some rays of Sunshine in..........
The watch you are buying comes with a guarantee...........and yes........the watches come back repaired.
As for the 004................it is a watch in constant development.................the engine and its various parts are constantly being tweaked..........if a 004 goes in for a minor service or repair , or a major overhaul , the 004 returns with these new parts or improved components..............................This is all part of being a 004 owner.............you become a part of watchmaking history and evolution..................yes , the 004 is significant enough to be a part of split second chrono history! , and is considered by many in the industry as one of the finest watches EVER.............
The company does not excuse any malfunctions , they accept and improve on it.............
Watches are like cars................so if you think Ferrari and Lambos are troublesome and moody( RM , Urwerk, AP Concept 
...................buy a Porsche or Merc. (LemaniaPatek 5070...lange...IWC)..............If you think all these cars are overpriced , go and buy a Toyota or Kia.(Seiko , Tag)
If you are happy with a c class merc......great..........If you want an SL65 black series and you can afford it.............brilliant................you dont need to justify your purchase to anyone other than perhaps your wife
Life is about freedom of choice based on ones own decision making process...................If you feel you will have post purchase remorse...........dont buy it...........just use the picture as a screensaver!
Different strokes for different folks ! Life is way too short to constantly find faults and be negative.
