PVD is a coating technique which is an alternative soution to electroplating (Gold plating) and is a technique which Rotary now uses due to its superior robustness.
PVD coatings are a better solution to traditional electroplated coatings as they have superior hardness and wear resistance, do not discolour or tarnish, and do not suffer under UV radiation.
The reason behind PVD's superior robustness is the process of application. Rather than the gold being applied to the bracelet or case through electric currents (as per electroplating), the gold molecules are attracted to the target item at high speed and collide on impace. In essence gold is trapped in the surface of the stainless steel item and is ingrained, therefore becoming part of the molecular makeup of the bracelet of case. PVD coatings are by their nature very thin, typically 0.3 micros, due to technology used to apply PVD, however this level of micron coating is still vastly more hard wearing than electroplating.
In conclusion, PVD is five times more hardwearing than electroplating.
All of the gold plate models within the Rotary Watches collection are PVD, totalling 39% of the entire range.
Rotary originally launched the 'Dolphin Standard' in 2005. This exceptional innovation was designed to remove the confusion surrounding complicated numeric measures of water resistance and simply provide consumers with the confidence that they could continue wearng their watches and still "swim and dive all day", since all of the 'Dolphin Standard' models could be safely exposed to water.
The 'Dolphin Standard' marque has new been replaced by the 'waterproof' guarantee. Put simply, a waterproof Rotary watch can go as deep as humanly possible and remain impervious to water.
Please note that all non-precious metal Rotary watches are waterproof unless otherwise specified.
Thanks to their swiss watch making heritage as well as the fact that their watches are waterproof, Rotary is offering a lifetime guarantee on all Rotary watches including the sub-brands. Each model is presented with a card-sized guarantee that can be registered by simply logging on the the Rotary watches website (www.rotarywatches.com) to record the watch and owner details.
In order to enjoy this continued guarantee all owners must send their watch back to a Rotary agent for a service every three years (prices may vary) and ensure that they provide a till receipt as proof of purchase when they send the watch back. Although servicing will be chargeable, it will contribute to the watch's long life through cleaning, lubrication, replacement of any worn parts, regulation and full testing.
After registering your watch you will also receive a letter/email every three years as a reminder that your watch is due for service a couple of months before the deadline.
