Named for the coastal town in southern Thailand that’s just a boat ride away from the Surin Islands and some of the best diving in the Andaman Sea, the HELM Khuraburi begs to visit far flung destinations. Featuring a Grade 2 titanium case and bracelet, automatic movement, screw-down caseback and crown, sapphire crystal, luminous sapphire bezel, highly legible dial and a 300 meter depth rating, the ISO 6425 compliant Khuraburi is a capable companion on any expedition. 

Available in two dial variations, with or without a date complication,
the Khuraburi also includes the NS1 Nylon Strap―an excellent option in the water and a casual, lighter weight alternative to the bracelet.
And with a standard 22mm lug width, this tool diver can be endlessly customized with aftermarket straps, including our own NS2 and NS3 nylon straps, LS1 and LS2 leather straps, CS1 canvas strap, as well as the RS1 and RS2 rubber straps.
