By TLex H2O Watches have partnered with German handmade strap-maker, Maddog, specialists in vintage ammo and baseball-mitt straps. H2O plan to use Maddog for their next major project due to launch this summer. The first 50 pre-orders will receive a FREE one-of-a-kind handmade leather strap. 
No two Maddog straps are ever the same; each have aged slightly differently from each other, each come from a different cut of each of the materials and each with the possibility of a number of stitching types using different yarns.
H2O have 5 Maddog strap series planned:
- Swiss ammo strap from WWII bag leather in dark grey
- Swiss ammo strap from WWII bag leather in black
- Swedish pistol holder leather from WWII in black
- US baseball mitt leather in brown
- US football leather
