The Ratio 1038EF102V Diver surprisingly is intended both for recreational and professional use. This 1000M diver's watch is fitted with a helium valve and a reliable Japanese Movement with Caliber - VX42E date-quartz analog movement. The dial has the logo RATIO upon it along with the symbol while the red-border minutes-hand is visible to the max! Topped with a sapphire crystal, the Ratio 1038EF102V Diver gets you many of the things that are usually available in the higher price brackets.

Elaborating further:Just like its inspiration, the Ratio 1038EF102V Diver is made to withstand diverse situations and harsh environments and is quite worthy of a praise. The Ratio 1038EF102V Divers' watch has significant protection against Helium, a constant issue for saturation divers. The gas can penetrate the glass along the edge where it meets the watch case. It increases internal pressure and can burst it open. So – the Helium-escape valve! Opening it releases the accumulated Helium back into the atmosphere

The way it looksThe machined surface of the watch case is fantastic. The brushed finish is fine, making its great tool-like design look even better! The serrated bezel is well-done; it is 60-clicks unidirectional. The clicks have a firm and satisfying feel to them and the lume-dot at 12 adds to its overall night-visibility.The screw-down crown at 3 and a screw down helium valve at 2each comes with distinctively different machined-finishes. It increases the grip, especially so under wet conditions

The perforated, polyurethane black dive strap is very comfortable. There's plenty of space for air to circulate and not let sweat build up. Its solid stainless steel buckle is unique; cool too. The lumed and chromed, rocket shaped hands are prominent time-markers; hard to miss. The lume is excellent with a glow for near-to 8 hours.
