Breitling Superocean Chronograph M2000 Written byMark BernardoSeptember 27, 2012 Many divers’ wristwatches include chronographs, but few of them can be operated at great depths underwater due to the risk of water entering the case when the chronograph pushpieces are activated. Breitling has hit upon a solution to this problem in its Superocean Chronograph M2000, which, as its name implies, has a chronograph that is operable at a depth of 2,000 meters underwater. The watch is the first to feature a patented magnetic push-piece system, in which the chronograph controls are operated via the metal of the case. Along with the screw-locked crown and the 4-mm-thick sapphire crystal, these pushers enable the wearer to use the watch at the extreme depth of 2,000 meters (or 6,600 feet) without the risk of water seeping in. The movement is Breitling’s Caliber 73, which has been chronometer-certified by the Swiss Official Chronometer Testing Institute (COSC). It is a self-winding, “thermocompensated SuperQuartz” movement, equipped with a 1/10-second chronograph, with 60-minute and 12-hour counters and a split-seconds hand for split times, as well as a date indication. The stainless-steel case is 46 mm in diameter and has a unidirectional, ratcheted, rotating bezel. The curved sapphire crystal is glareproofed on both surfaces. The dial is in Breitling’s “Volcano black,” with silver-rimmed subdials highlighted in red (as shown), blue, green, or black. Options for the strap or bracelet include Barenia leather, “Superocean” leather, perforated “Ocean Racer” rubber,” “Diver Pro” rubber with raised central ridge, and Breitling’s “Professional” steel bracelet. The price for the model shown here is $4,485. (Click on watch photos to see larger images.) Receive all the news, features and reviews from WatchTime for free!
