Review of the TX 730 Flyback Chronograph

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. The addition of a sapphire crystal and 100 meter water resistance is a welcomed bonus given the price.The Edifice 700 is controlled like just about every other Casio: a button on each corner of the case has a contextual use given which mode you are in. Modes include: Timekeeping. Stopwatch. Countdown timer. Alarm. Dual time (to track the time in another time-zone). Hand sync mode.That's a pretty stacked feature list. I loved having a different time zone displayed on the screen for when I travel, and a countdown timer is surprisingly useful. One of my favorite features is probably the EL backlight. It's a "reverse" backlight which illuminates the numbers rather than the area around them. Not only does it look extremely cool, but it's very practical, as well, since it makes the watch unusually legible in the dark.
