Diver One D1-500 ND713RD
“Divers working in the North Sea are made up in teams of three and on any working dive you have a diver 1, diver 2 and the bellman, diver 1 controls the dive and this is where the name for the watches come from, diver 2 is there to make his job easier, the bellman tends the divers from the diving bell and the divers work in the water for a maximum six hours, a normal saturation diving system will house four teams of three divers covering the full twenty four hours of the working day stopping only for bad weather or crew changes, the work period for the divers is 28 days including decompression.“
Paul took the already tough Diver One design and made it into the classy ND713RD. Like the previously reviewed Diver One, the ND713RD comes in a 40mm case. With a 500m depth rating, the ND713RD features a 1mm case back gasket which ensures it’s water tightness in diving conditions. The “classy” D1 features a black PVD coated 316L surgical grade stainless steel case. The case includes everything I expect a functioning dive watch to have. It has a screw down crown, rotating bezel with a lume pip, thick domed sapphire crystal and a gas release valve.
The gold details weren’t just reserved for the details on the dial, but also on the Ronda 713SM movement. The movement is a gold plated 5 jewel Swiss made movement, with a long battery life and features a EOL indicator. I love that the movement is a clean non date movement, as opposed to a movement which date window takes away from the overall flow of a dial. The generously sized sword style hands allow for great legibility even when conditions are not optimal. I wasn’t worried about the legibility of this watch since Paul tests his watches himself in the murky, dark waters of the North Sea. The gilt hands and printed markers are set beautifully against the gloss black dial. The dial is kept minimalistic as well with the limited amount of printed text. The text was kept to the Scurfa name logo under the 12 o’clock position and Diver One just about the 6 o’clock position.
The 40mm by 47.7 by 14.4mm case is equipped with a Heliox escape valve which was built into the watch case located at the 9 o’clock side. The escape valve has been tested by Paul Scurfa himself at different depths and gas mixtures, with the deepest decompression being 154 metres to the surface. This is why I love Paul’s watches. People ask me why I review his watches since they aren’t a style a typically go for. They also know how I am bored with the watch industry as a whole and extremely tired of rehashed designs. It’s the extreme amount of testing that Paul puts into his watches that draws me to them. They are affordable, they are tough and they are packed full of tested features. Paul personally tests his watches in the harsh conditions of the North Sea.
