The New Rolex GMT Master II

I've actually opened one of these and regulated it; it's well-made and quite sturdy. I was impressed, and enjoyed wearing it for a day. The orange second hand is wonderful, and I really like the uncluttered face and dramatic hour & minute hands. With a street price of around $600, it's a good price for a solid Swiss watch of high function and durability. The Fortis SquareMost Fortis watches look a lot like the Flieger, but they've recently branched out a bit and introduced the simply-named "Fortis Square". It has the ETA 2836-2 automatic movement, and looks quite a bit like the Flieger, but changes to a dressier 38mm square case and leather band. I personally prefer watches with day and date, so I like how this looks. Features include a stainless steel case, AR-coated sapphire, screw-down crown, screwed caseback, and water resistant to 100m (330 ft).But that's just the beginning. The case and dial are filled with silicone oil which, having the same refractive index as the sapphire, removes reflections and makes the dial visible from all angles and avoids the underwater "mirror effect". Sinn had to use quartz here because no mechanical movement can function while immersed in oil.But the silicon oil isn't just for visibility. In conjunction with the construction of the case, and a special gasket system, the oil allows the watch to withstand enormous pressure. For the sake of comparison, a Rolex Submariner is rated for200-400 meters (about 650 to 1,300 feet) of depth, depending on when it was made, and a Rolex Sea-Dweller isguaranteed to 1,200 meters (about 4,000 feet).
