IWC Aquatimer Chronograph 44mm – IW376803 – Full Set – Just Returned from IWC Full Service – 2-year IWC Warranty!

If you want serious diving watch wrist presence, along with the reputation of the world-renowned International Watch Company (IWC), this is the watch for you! It epitomizes the high-end sports dive watch, while still conveying the luxurious feel you’d expect from an IWC. Details like its unique external/internal rotating diver’s bezel and rubber strap with IWC’s patented quick-change technology keep it pushing the limits of innovation in the watch world. The beautiful black and white dial with the impressive brushed finish on the case lugs will keep you distracted for years to come. Pair’s well with a tailored suit all the way to a swim suit!

The watch just returned from a full service at IWC so now is covered under a 2-year warranty directly from IWC! All receipts and papers from this service with warranty details are included. This is the best way to buy an IWC to save you money and get an amazing piece with the confidence of knowing it is covered from any issues. Watch is in incredible shape with very minor signs of wear only noticeable in bright sunlight or with a jeweler’s loop. This was a single owner watch and comes in the full IWC box set with everything included from original purchase at the IWC Authorized Dealer. Hang tag, box and booklets, microfiber cleaning cloth, etc. Warranty card dated 2015. Even comes with the leather travel IWC watch case that is provided with the IWC service.

I’m a passionate watch collector and retailer. I love everything about timepieces and thoroughly enjoy helping others discover the enjoyment of this pastime. Whether it’s helping you find your grail, or the next watch to fill that empty slot in your watch box, I consider it a privilege to be part of your journey. My aim is to be as fully transparent as possible in all my listings. Watch industry references available upon request. Please let me know if you have questions about this watch or any of the others I have for sale. I look forward to helping you secure your next timepiece!

Also, ask us about our free bottle of Klender Cellars Cabernet from our family winery in California, shipped to you with purchase of this time piece. Retail value of $85 + shipping per bottle!
