Decided to go with a Sinn after long and hard thoughts. The models I like are the Sinn U2-T EZM 5 Fully Tegimented on Bracelet (3300), Sinn U2 Black EZM 5 on Bracelet (3400), Sinn U1 S Black Fully Tegimented on Bracelet (2600), and the Sinn U1-T Fully Tegimented on Bracelet (2600). All are plus tax too. Believe all those are sold out for the time being. Are the U2's worth the extra 700-800 and what about the need for service and how long before to do so? Also, is the only service center in Germany, was to there was one her in the USA? Thanks
Lastly, are these worth the price all things considered and/or do they lose huge value once worn?
