Marine Chronometer OriginThe name of the new Rolex Sea-Dweller Replica timekeeper - Rolex Sea-Dweller Replica is the Italian phrase which means the Admiral of Time. A probable reason for such name is one of its exquisite and very demanding traits - the presence of a detent escapement which is quite different from Swiss lever escapements which are omnipresent in contemporary timekeepers. This type of escapement first arouse in the 18th century in the era of great naval expeditions. Its main purpose was to enable better accuracy which was of paramount importance when navigation on the sea depended on a punctual timepiece. The improved performance of detent escapement is based on three of its traits: the minimal interference with the balance that oscillates, its improved energy efficiency and the fact that it does not need any lubrication. These characteristics are based on its very construction. Contrary to its Swiss lever counterpart where the said lever transfers the energy from barrel spring to the balance in two impulses, a detent escapement creates just a single impulse which regulates the amount of energy which is transferred from the barrel spring, as well as the energy's redistribution to the balance. In yesteryears, this was a crucial difference that resulted in better accuracy.
Despite its superior precision, detent escapements are still extremely rare in wristwatches because they are very difficult to create on a smaller scale and because of some of the common problematic issues that are associated with their functioning. One of the crucial faults of this sort of escapement is its excessive sensitivity to shocks. Rolex Sea-Dweller Replica overcame this problem by altering the design of a detent arm. It is supplied with an added safety roller which prevents the slipping and unlocking of the escape wheel. Another possible danger is the inclusion of a cylindrical hairsping that was used in old marine chronographs. This solution is also characterized with better precision, as well as a greater risk of malfunctioning.Tudor Replica Watches The potential excessive rotation that can occur when a cylindrical hairspring is included was neutralized with an addition of a pinion that connects it to a security wheel.
Additionally, the manually-wound movement of the new Rolex Sea-Dweller Replica watch that beats at a slow rate of 14,000 vph is supplied with a constant-force device, a mediating spring located in the movement's gear train that ensures that the regular torque is transmitted to the escapement regardless of the state of its 48 hour long power reserve.
