The Orient 300M Pro Saturation Diver SEL0200 is another professional diving watch that I own. Upfront I have to admit it that this watch is by far, the best professional diving watch currently available on the market in terms of capability and value-for-money.
The Pro Saturation Diver comes in a stainless steel case with beautifully polished sides and brushed lug tops. The case is large, measuring 45.4 mm without the large signed screw down crown. With the crown, the case diameter is 50.4 mm. Case thickness is hefty, at 16.9 mm. Lug width is 22 mm.
