The Group B Series 2 Windup Edition is a Worn & Wound boutique exclusive in a new colorway. In contrast to the bright, brushed steel of the normal models, the Windup Edition features a dark titanium gray PVD coating over steel on the bracelet, mid-case, and crown, with the bezel and case back remaining solid titanium.
It is true that NTH watches emulate other, more established brands. They make no bones about it. But, as a line that plays off the homage design theme there will be a lot of watch snobs that dismiss NTH out of course. On the other hand, if you can put aside brand prejudice and take a close look at a watch for what it is and how its made vs. what it cost, NTH makes a good argument for that spot on your wrist.
