I agree 100%, these Clockwork Synergy silicone bands are far and away my favorite for the Pebble Steel. Incredibly comfortable on the wrist and the little tube added to the band where it connects to the watch makes for a firmer (perfect) fit. I purchased both the black and gray bands and am thrilled with both. The black buckle is another great feature, making the Black Matte Steel look even better on the wrist. Plus, the free tool they give is absolutely essential, making it very easy and fast to swap bands. They ship very fast, both of my orders were in my mailbox exactly two days after purchase, and the price is very affordable - less than $20 for each band (with the tool!)
I too would buy Clockwork Synergy leather bands for the Pebble Steel and am especially interested in darker colors - perhaps a dark brown which would look perfect on the Black Matte Pebble Steel? I would also buy darker color bands in the silicone, again, would really like a dark brown or variations of black. Thanks again for such a fabulous product and excellent customer service - looking forward to the leather bands!
