This is my 3rd try at finding a sports chronograph that I like in the last 6-years.
In 2009, I purchased my first Sinn chronograph; a Model 756 Diapal. I loved the simple functional graphic design of its dial and the bulletproof tegemented case and bracelet. Ultimately, I ended up selling it in 2011 because I missed having running seconds, poor lume, rough chronograph pushers and difficult to read 2nd timezone hand.
In 2012, I purchased an IWC Pilot Spitfire Chronograph. I was attracted to its clean aviation look, the raised numbers and depth of the dial, its decent lume (compared to the 756 Diapal)an in-house flyback calibre and a bracelet with a micro-adjustment. I sold it in 2014, because the gimmicky date window began to bother me and the way the lugs rested on my wrist in a manner that never felt quite at home on my wrist.
So now we're in 2015 and I am diving back into the chronograph pool with another Sinn (actually, my 3rd Sinn; I also had a U1 Tegemented That I gave away to a family member). I just ordered a Model EZM 10 TESTAF from a (or I should say "the") US Dealer. It is not inventoried, so it is being made for me at the factory. It was for many of the same aesthetic, engineering and material reasons that I was originally attracted to the 756 Diapal. I am hoping that the lume has been improved and the pusher action is less jerky.
I will make a posting when it arrives in February.
