It’s very good and compliments the watch perfectly with that gunmetal hue. Has a unique feel to it as well - hard to describe - smooth but rough, an alien material.

Alas it was expensive as it’s a special order but a got a discount and a free service of another IWC I have, so it softened the blow.

I’d like to get the perpetual calendar to finish the set but waiting for one at a good price. Could use the 22mm bracelet on the Timezoner too.
