Grand Complications 40mm Rose-Gilt Dial Men's Perpetual Calendar Watch

Do keep your watch dry as much as possible and stick to the recommended water- resistant guidelines to ensure water damage does not occur to your timepiece. Water resistant watches on leather straps should be kept out of water to preserve the strap. If salt water comes into contact with your watch, it is always a good idea to rinse the watch in clean water to ensure all the salt residue is removed. Wherever possible, never expose your watch to extreme temperature changes or excessive shock

Wind automatic watches a total of thirty to forty times at the crown to guarantee optimum torque. Watch parts such as the crown, the case seal and other water resistant parts may need replacing every one to two years to ensure [n1] full water resistant capabilities. You should also ensure that the watch is kept away from hard surfaces to avoid scratching the sapphire crystal glass front and case backs (although offering a hardness of 9 on the Mohs scale -  this will only guarantee scratch “resistance’ as opposed to scratch 'proofing”).

Servicing in accordance with the manufacturer's schedule will ensure optimum health for your wristwatch. Whether still in warranty or not, we still always recommended periodic servicing or your watch. Not only will a watch sometimes need re-sealing, but adding new oil may also be required. Over time the chemical make-up of the oil which works in conjunction with bearings made from jewels, will change. This means that the springs within the watch will not be powering the drive train properly. Adding new oil as part of a watch service will ensure that the crown winds smoothly without a “gritty” feel, whilst also enhancing accuracy and a better release of power from the spring coils. Quartz batteries are designed to last up to two years, and so a complete battery replacement is recommended after this period of time.
