Automatic movements can be damaged by the automatic rotor moving out of place if the entire movement is subject to severe shock - such as a fall. By locking the automatic movement, you of course prevent the watch from self-winding, but you also protect the movement from types of serious shock. omega seamaster replica claims that with the Amortiser system engaged (which the user must do manually) the watch can survive a fall from 5.2 meters (in their tests). That is sort of a big deal. In order to lock the rotor, you must first take the watch off your wrist, and then go to the caseback of the watch and literally turn the inner part of the caseback from the "Off" to "On" position.
The brilliant part about having a power reserve indicator on the dial is that if you choose to have the omega Speedmaster replica engaged for a long time, you can a least know the power left on the movement so that you can manually wind it if necessary. So for that reason, the Amortiser works really well with a power reserve indicator, because with it engaged, an automatic watch is turned temporarily into a manually wound watch. It is thus impressive that even with this moving caseback part, the http://www.modserap.com/cartier-roadster-replica-australia-for-sale.html has 200 meters of water resistance. It also has shock resistance of up to 7,500 Gs and 4,800 A/m of anti-magnetic resistance.
The bracelet on the Omega Seamaster Aqua Terra is very well made, and there are small micro-extensions on each end which come in handy. Inside the Omega Seamaster Aqua Terra is the Omega caliber RR1201, which is a base Swiss Sellita or ETA mechanical movement with, of course, some modifications by Omega. For me, the Omega Seamaster Aqua Terra is a great assortment of features and design cues that feel very satisfying together, if you are looking for a high-quality and useful men's sports watch (that also happens to be rather attractive). Even so, Omega will only produce the Omega Seamaster Aqua Terra as a limited edition of 500 pieces.
It goes without saying that all Omega Speedmaster watches will feature tritium gas tube illumination. Most of the tubes will glow orange with a single blue tube at 12 o'clock. Orange is said to be a signature color Speedmaster - especially on their instrument panels, so the watches try to use this when possible. Last, another interesting feature will be part of the Omega Speedmaster watch collection. This feature showed up on a Omega watch last year, and is called the "Amortiser." It allows you to press and screw down the caseback of a watch to lock the automatic rotor into place. This is meant to be used when the wearer expects the watch to endure shock or trauma to help protect the movement. The wearer must then disengage the Amortiser for the watch to continue automatically winding.
