Its not 100% scientific i know but.
I've bought 2 brand new identical watches. The only difference being dial colour combo.
There both Xezo Air Commando's with miyota 9015 movement's. One is the blue faced dial model no d45-bm, the other white/blue dial version model no d45-ss They both arrived today.
I wound them both the same and taken initial measurements on my timegrapher.
Then after 2 hours I've taken more precise measurements and I shall take measurements again tomorrow using the exact same method.
On initial measurements taken right out the box both had amplitudes of 280 degrees (lift angle 51)
Then after 2 hours running at full wind both on each wrist (which felt awkward) I fully wound them and taken measurements using exact methodology each time.
Blue dial. Rate +12spd, Amplitude 288, Beat error 0.0
Whit/blue dial. Rate +5, Amplitude 285, Beat error 0.1
Both will be measured at the same time approx 12pm (GMT) tomorrow. Using the same method.
I'm not wanting to wear 2 watches, so I thought I would alternate between them each day and fully wind them before measurements.
On another note both watches are stunning imo and a bargain over at Amazon. Pictures and a review thread will be made in due course.
