How collectable are the SEA DWELLER 4000 ref.116600 (SD4000)?

2017 marks the 50th Anniversary for the Sea Dweller. Originated as the upgrade version of the Submariner, in collaboration with COMEX; it is goes on to become an entire linage by itself.

Ref. 116600 was unveiled at 2014 Baselworld. To the surprise of many, it was discontinued this year (2017) making way for ref. 126600 (43mm with cyclope). Ending a brief and unremarkable production run. A smaller case (comparing with Submariner and Deepsea) coupled with a higher price tag, make sales reasonably slow. Perhaps, these are the real factors that made Rolex decide to kill this reference, for good…

On the hindsight, this create an interesting scenario for Rolex collectors:
1) Shortest production span for any of the pure stainless steel sports Rolex, no different dial variants discovered so far, homogenous batch.
2) First Rolex professional watch in the “ceramic bezel” era to be discontinued.
3) Most importantly, how many 116600 really existed?

Already the price for 116600 in the preonwed market is already surging. Collectors and dealers have realize its potential. Value of watches is always a balancing act between the supply and demand. We now know the 116600 supply is now finite and dwindling. How high it will go perhaps will depend on the future demand….




Rolex Anchor refers to those miniature anchors that’s included with Submariner  & Sea-dwellers watches.  In 2005 (F series) Rolex decided to stopped issuing Anchor as an accessory with the Sea-Dweller ref. 16600 and  Submariner ref. 16610/16613/16618.

Nevertheless owners of these old watches will love to include them with their watches, having it as part of “complete” package (set).

We believe Rolex first began including the anchor with the early generation Submariner models ref. 6536 & 5508. They are known to be issue with 100m/330m Anchors.

Vintage 1680 or 5513 Submariners with 200m/660ft anchor are rather well documented.


Sea-Dweller 1665 anchor, however was of a rare and curious thing. Rolex did a trick: they stick a plastic green dot over the standard Submariner anchor. Green dot of 200m & 610ft was glue over the depth rating of the 200m/660ft anchors.

The introduction transitional models Submariner 16800 and Sea-Dweller 16660 in the early 1980s, when Rolex started using sapphire as replacement to plexi. The depth rating increased: Maybe the anchor with the new depth rate probably wasn’t ready in time. So Rolex used the same old trick once again: they stick a plastic green dot on top of the old rating. Green dot of 300m and 1000ft was glue over the old 200m/660ft anchors: and we have a transitional Submariner anchor. Similarly for 16660 it’s anchor has green dot of 1200m & 4000ft.

The modern Submariner anchor: The silver 300m/1000ft anchor (below) is the most commonly found anchor variant, as it was included with the stainless steel 16610/14060/14060m and two tone Submariner 16613 variants, for a period of one and a half decade.


A much rare Gold-plated Submariner Anchor (see insert) is for the full gold Submariner 16618:

The modern Sea-Dweller anchor: The silver 1220m/4000ft anchor (much rarer and hence cost double) are a standard issue to 16600 till 2005.



One of the most interesting item that Rolex has ever issued with a Rolex watch. Seem like most of the preowned 16600 watches were traded nowadays are without this tool set. They could be in the hands of collectors or quite simply discarded/lost in the early days. The mini SCREW-DRIVER (ref 2100) has the best fit to remove the screws on Rolex bracelet. This could quite explain why so many of these tool sets has the screw-driver missing.
Leather texture and leather holder layout varies slightly over different period.
items found with a complete kit:
1) Screw driver, caps, and a spare black screw
2) Buehlmann Table
3) extra extension folding links, spring bar, and black screw
4) Leather holder
Possible others items it can hold: calendar, service booklet, warranty paper
