Bought the blue and white single-pass strap for my Citizen Promaster Pepsi and I'm really pleased with it. The colours work extremely well with the blue dial and bezel, and the white centre stripe gives it a nice bit of contrast without being too loud. The single-pass design is comfortable on the wrist and I much prefer wearing the watch this way compared with the original strap. The hardware also looks and feels nicely finished and the strap sits well even on a fairly substantial dive watch. Very happy with the combination and it has completely changed the look of the watch. Would happily buy another in a different colour.
