Rolex “SD43” Sea-Dweller 50th Anniversary Edition “MK1” Dial

For sale is a MINT (no scratches, dings, or dents on case or clasp), freshly RSC serviced, warranty remaining, 2017 “Red Letter” 126600 50th Anniversary Sea-Dweller with the rare “MK1” dial. What makes this particular watch unique is the dial which has the “Swiss Made” printed without the Rolex Coronet at the 6 o’clock position. This is the configuration that was originally displayed by Rolex in the booth as the 50th Anniversary Edition at Baselworld 2017, as seen online. Not even a full year later, the dial was revised, and the original as displayed here was discontinued mere months after its initial release. This was done to indicate the new update to the new 32XX caliber movements going forward on all new production watches. This watch is one of the only watches Rolex produced without that coronet that has the new 3235 movement. At Baselworld 2018 the coronet was added in-between the words “Swiss Made”. Additionally, the font was changed and the “1” in the 1220m depth meter rating was changed as well changing from the original “stick” font to the serif font “1” with notch. Some refer to this model as the true 50th Anniversary Sea-Dweller as it is EXACTLY as it was displayed at the Rolex reveal at Baselworld 2017, and consider the changing of the dial as a wink from Rolex to those who purchased during the actual 50th Anniversary year of the Sea-Dweller. A simple google search for “SD43 MK1” will present plenty of details regarding the rarity of this dial configuration.

This watch was RSC serviced in April of 2021 and has a fresh 2 year factory remaining warranty. This watch is not being worn currently. You will receive the full kit to include original factory warranty card, service warranty card, inner and outer box, white hang tag, all links, green Rolex Box, AND service paperwork from RSC Beverly Hills. This will continue to be a true collector piece well into the future as market prices have already risen several thousand for the true 50th Anniversary release Sea-Dweller. Comparable listings from Crown and Caliber and DavidSW are currently around $16,900 and sale of item includes state sales tax. I have only seen one on each site, and I will not include state sales tax. There is another listed on Chrono24 in the 15K+ range, but it has significant damage to the lug case edge from an impact. This listed watch here is pristine.

Please don’t hesitate to reach out to me at for any questions. I have more pictures available upon request and will be more than happy to take more. I will provide my phone number upon request to speak more directly if desired, or to meet face to face if local. Additionally, I will set the watch to whatever time you like and provide photos, take video, or display the watch live if requested. Bank wire only at this time. I will provide shipping via FedEX Two Day or split the cost for overnight if desired.


**IMPORTANT NOTE** I will be away from home from 6/14-6/25 due to travel for work, if you make a purchase during that timeframe please understand that I will not be able to ship it out until I return, as the watch is stored in my home safe. I will ship as soon as I return if this occurs.
