So the 10 year service might nit be far off. Kinda ties into the discussion on HOME about getting your watch serviced.
There's a great review on here of a 726s watch - where they used to dismantle them & conclusion is pretty much that.
Urushi while not cheap - or even close to a Seiko 5. They are fantastic value & not hugely expensive - probably cheaper than a service on some.
As I've said in passed its all about the dial - & it is glorious 
I certainly encourage you to consider one when the funds allow - I've not regretted getting it.
Cheers
