http://www.thewatchbox.com As its name implies, the Omega Seamaster Aqua Terra line is designed to take the Biel/Bienne giant's iconic "Seamaster" label into polite company beyond the wind and waves. While still a sports watch, the Seamaster Aqua Terra 150m Co-Axial is a diver with discretion and taste. During the 2000s, Omega diversified the dive-oriented Seamaster line with the Planet Ocean (larger cases, retro design cues) and the Aqua Terra (greater formality). Aqua Terras dispense with rotating bezels and Kraken-hunter depth ratings in favor of elegant details and thinner cases. This Aqua Terra 150M features a two-tone stainless steel and rose gold tandem that imparts elegance without putting precious metal in harm's way (e.g., contact points such as the bracelet and lugs). A refined metallic tobacco dial is visually consonant with the rose gold bezel, and the dial's vertical "teak concept" stripes resemble the pinstripes of a premium suit. Omega's exclusive co-axial escapement is in play, and it's easy to forget that this now-familiar technology still represents one of the few true "alternative escapement" technologies available under $100,000. Naturally, it's also a COSC-certified Swiss chronometer. The rest of the Omega Cal. 8500 movement is just as compelling. Released in 2007, the device remains a stunning value and formidable statement of watchmaking prowess. Its elaborate finish and 55-hour power reserve endure, but the deal is sweetened through the addition of amagnetic and shock-resistant silicon. Gunmetal gray silicon hairspring and balance wheel can be seen in action on the robust full balance bridge. This movement is built for the long haul. Available from thewatchbox.com with full boxes, papers, and technical manuals, this Omega Seamaster Aqua Terra 150M Co-Axial Chronometer is as close as one can get to a do-it-all luxury watch.
