IWC Grande Complication Minute Repeater Perpetual Calendar Watch Repair


Every day at Gray and Sons customers bring their Rolex, Patek Philippe, Omega and Cartier watches (just to name as few) for repair and servicing, but once in a while a rare watch comes in. Rare not because of its brand but for its elegance and engineering which makes this watch a true work of art. From simple repairs such as adjusting a leather bracelet on a Christophe Claret watch to a full overhaul on this limited edition 18K Rose Gold IWC Grande Complication Minute Repeater Perpetual Calendar, Gray & Sons will do it all.

As you can see from the pictures, this sophisticated yet elegant watch came to our store for a complete overhaul. Regular maintenance on these kind of watches, should be done every 4-5 years. All lubrications need to be changed in order to keep all moving parts on the watch in pristine condition. The IWC Grande Complication features a 42.2mm 18K Rose gold case with a high polish finish and a beautiful ardoise dial displaying a perpetual calendar, year display and perpetual moon phase. Powering this IWC we find a unidirectional automatic winding Caliber 79091, 75 jewels movement, truly one of a kind. During the overhaul and detailing process our watchmakers, with over 150 years of combined experience, disassemble the movement. By first removing the calibre 79091 from its 18K rose gold case and using precision tools, the movement is completely taken apart and placed in special baskets designed for our Tempo ultrasonic 4 step cleaning machines. During this process with the help of powerful cleaning fluids and strong ultrasonic vibrations old oils are removed from every small part of the movement. After this step is completed, it's up to the watchmaker and his years of experience to assemble the calibre 79091. This particular movement is not only sophisticated due to its chronograph functions and perpetual calendar but for its minute repeater.


Gray & Sons’ independent Audemars Piguet repair center is regarded by many as the premier watch repair center in the United States. With over 150 years of combined experience, our master watchmakers service, maintain, and repair all fine luxury watch brands.


While the movement is being worked on, our in house master polisher details this beautiful 42.2mm 18K rose gold case. This is a process that requires a lot of time and experience since major damage can result from over-polishing. Once this is completed and the movement has been reassembled, it's the watchmaker's job to re-case the movement. During this step all gaskets are replaced to ensure proper waterproofing. This step is very important since we don’t want our client watches to suffer any water entrance. Once assembled the watch undergoes a very strict quality control. This particular movement holds a 44 hour power reserve. Our repair shop manager checks this very thoroughly to ensure that the watch will run continuously for this full power reserve time. After completing this process the watch is ready to be back on our client's wrist.
