Up for sale is my 116600 Sea-Dweller, also known as the SD4K, also known as the last “real” Sea-Dweller. At 40mm the watch is extremely wearable compared to its 43mm contemporary. It has what I consider the perfect bezel-to-dial ratio. It’s laughable to say that any steel Rolex is “rare” but the 116600 is as close to rare as any, according to the Nicholas Foulkes Submariner book fewer than 30,000 units were ever produced for this watch making it much, much, much more rare than a garden variety Submariner.  Purchased NOS from a trusted dealer last year the watch is in worn condition. The watch has never been polished and includes everything: beige outer box, green inner box, card, hangtags, and original links.  Please let me know if you have any questions or would like to check out additional pictures. I’m selling to fund another irresponsible purchase, night vision.  Asking $12.4k. Payment via wire, shipped via FedEx with signature within CONUS free.    Timestamp: [https://imgur.com/a/69upyn7](https://imgur.com/a/69upyn7) Pictures: [https://imgur.com/a/9wAuRHi](https://imgur.com/a/9wAuRHi)
