# 1955 IWC 18k cal. 89 Video: [https://youtube.com/shorts/kUlDOnhiqnw?feature=share](https://youtube.com/shorts/kUlDOnhiqnw?feature=share) Up for sale is this very nice example of an 18k gold vintage IWC from 1955 in a very rare dial and case combination. This piece utilizes the legendary IWC cal. 89 manual wind movement, and this example of that movement is in incredible condition. It looks virtually new, by far the cleanest example of one this age that I’ve ever seen. The case is an oversized 35.5mm, with a 42mm lug to lug length and 9.5mm thickness (including crystal). Watch is shown on my \~6.75” wrist for reference. Movement is in very good running condition and winds and sets smoothly. Case hallmark is bold and the case appears unpolished with nice sharp edges. Dial is original with very light patina. Case and movement serial numbers align closely as they should. **Imgur album**: [https://imgur.com/a/1955-iwc-18k-cal-89-manual-wind-oXAKe6s](https://imgur.com/a/1955-iwc-18k-cal-89-manual-wind-oXAKe6s) **Timestamp**: [https://imgur.com/a/B8OIytu](https://imgur.com/a/B8OIytu) I’m asking \[SOLD\] ~~$1,695 shipped~~ in the US via wire, Zelle, or Venmo. I will ship internationally and only charge the difference in cost on top (Wise accepted for international payments). I’m not interested in trades. Feel free to reach out with any questions!

Great experience & transaction with mattmcmhn

Extremely flexible with my requests and questions. Adjusted the 2 day shipping to overnight with reasonable price adjustment. The watch I received "Tudor Black Bay" is absolutely as described and pictured with the box/papers. A 100% perfect transaction. Thanks again Matt! Adam

Smoothe transaction with Mattmcmhn!!

Just purchased a Pelagos from Mattmcmhn! Everything was better than stated. Matt immediately mailed the watch upon receipt of the funds. He answered all my questions and everything was better than I anticipated. I will purchase from Matt anytime!

mattmcmhn (Matt) is a soloid seller!

I just received a Rolex Explorer II from Matt, very smooth deal. The watch is better than advertised. I'd have no problem buying from him again. My only complaint, it was a tossup between my sawzall and the Jaws of Life to get the package opened, very securely packaged!!
