I've been looking for a good dive strap for my Christopher Ward C60 Trident Lumière. I knew I wanted an FMK Rubber strap. I tried several of the current offerings but wasn't quite satisfied. This Divecore x StrapHabit HP Professional Diving Watch Strap checked all the boxes. First, it is extremely comfortable, having a wavy texture on the interior and real vents that provide ventilation. It is a true diving strap with the mono-accordion design. It fits perfectly - which is not always the case. And finally, it looks great on my watch! A great 300 meter diving watch deserves a great strap! This is definitely a great one!
