The Oceanus OCWM800TBA

We've become big Sinn fans here at WatchReport, and today I learned of a new model, the 657. Available in black chromed steel (shown) or stainless, this update to the 657 adds some features of interest:Updated bezel design, more durable and more readable markersSize increased to a more modern 40mm by 12mmAdded a black chapter ring around the dial for readability.Those are just the new features! In addition, it's a bulletproof watch for extreme environments:Anti-magnetic to 80,000 A/m, which works out to about 1000 Gauss, or 0.1T, the same as the Rolex Milgauss. As with the Milgauss, Sinn used an iron dial and soft iron movement casing inside the watch to achieve this.Double-sided anti-reflective-coated sapphire crystal, very scratch resistant.In regular time keeping, the six o’clock dial keeps track of the seconds as they pass and becomes a sub second measure when the chronograph is activated. The nine o’clock dial portrays 24h time, an essential feature on any globetrotters watch. Lastly, the city code for the world time function is wrapped around the chapter ring and uses the second hand for readouts and selection. The challenge in building a watch like this is balancing the geeky information it provides in a ***, understated and classy way that keeps the watch fashionable and flexible. You may be a total nerd for the technology implemented in this watch, but the M800 will keep your secret.
