Orient introduced the Pro-Saturation Diver as an answer to Seiko’s Marine Master and thereafter, watch enthusiasts are into a never-ending debate regarding the two. However, the Marine Master got a lot of spotlight till now, so it’s time for the Orient 300M Professional Diver automatic. Pro-Saturation is the name it goes by.

Frankly speaking, it’s a very tough decision to make. Both are equally good, but the only extra point the Pro-Saturation Diver scores are in terms of price. It costs tad lower than the Seiko, but then again, that’s not what squelches the debate. There are other aspects to the Pro-Saturation Diver as well the price factor. These points are grounded in reality and not just a flight of fancy.

Going back some five years (2010), we see the Orient Mens Watch seeing the daylights but in 2013, the Pro-Saturation revealed itself as a new version. The classic saturation diver came in classic matte white this time, blending style with utterly utilitarian aspects. It is of a distinct quality and the EL02003W, featuring an in-house movement (Caliber: 40N5A), is wind-able unlike the rest of the Orient movements. It’s hackable, too; which adds more to its credentials. It consists of 22 jewels, beats at 21,600 vph and accurate to +15 seconds per day. It also has a heavier rotor, specifically designed to wind the mainspring underwater. The other upgrade in the Pro Saturation Orient Watches-click unidirectional bezel and the whole package is now a truly unique one!

The Pro Saturation Diver is meant for mixed-gas diving. While some might ask questions on the absence of the Helium-escape valve, but that’s not required; the case has been designed so that it prevents the build up of helium gas within. So, an external valve is no more a requirement.

In its appearance, the Pro-Saturation Orient Watches Online a beautifully polished, hefty and substantial stainless steel case with the lugs brushed on the tops. At 45.4mm (without the large, signed screw-down crown), it’s suitably sized for underwater operations. Its wrist presence is for them who are strong at heart!
The Pro-Saturation Diver sports a flat, anti-reflective sapphire crystal of around 5mm thickness and a slightly bevelled edge. This provides for a perfect fit with the bezel, which is itself a beauty due to its ceramic-styled bezel. The action is super-smooth, just like the viscous fluids flow. At the top (12’0 clock) there’s a lume pip, but not the other markers. The large markers on the dial; however, are brightly lumed.

Let’s talk about the power-reserve meter now. On the upper right quadrant of the dial, it is slightly recessed and silver coloured. It measures 40 hours, which is max and is one complication that’s useful as well as looks good. At least, you’ll never go diving when the power reserve is at the rock bottom!
