Forum rows are posts on Reddit r/Watchexchange, RolexForums and WatchUSeek that the seller marked sold. The amount is the listed price when marked sold, not a confirmed sale price, and forum rows do not feed our price.

Median price per month or quarter. A point needs at least 3 records in its month or quarter; a gap in a line means too few records, and nothing is filled in. Forum prices are the price a seller listed on Reddit r/Watchexchange, RolexForums or WatchUSeek when the post was marked sold, not a confirmed sale price.

The Sea-Dweller Deepsea 126660 at a glance

In our catalog, the 126660 is a Sea-Dweller Deepsea: a 44 mm case in stainless steel. Our sources don't state its production years, so we don't list them.

What our catalog records for it:

  • Case: 44 mm, stainless steel.
  • Bezel: unidirectional rotating bezel with black Cerachrom insert.
  • Dial: d-Blue gradient (blue to black).
  • Movement: calibre 3235.

It is one of 7 references in our Deepsea catalog. This page covers the Rolex 126660 D-Blue, one version of reference 126660; the Sea-Dweller Deepsea 126660 page covers the reference as a whole. To compare prices, the nearest Deepsea references by case size are Deepsea Challenge 126067 (RLX titanium (grade 5 titanium)), Sea-Dweller Deepsea 126660 (stainless steel) and Deepsea 136668LB (yellow gold case with RLX titanium caseback).

What recent sales of the 126660 show:

  • Fair value now: $9,550–$15,900.
  • Midpoint of recent market prices: $12,700.
  • Newest observation: October 17, 2026.
  • Observations behind the estimate: 213.

What affects the price

Condition. Here is how condition splits the sales we have (a grade with too few sales shows no range):

  • Unworn: $12,300–$16,600.
  • Excellent: $10,700–$14,500.
  • Good: $10,700–$14,500.
  • Fair: not enough market data yet.

Service history. Paperwork showing when the calibre 3235 was last serviced, and what was replaced, gives buyers confidence.

Bezel and insert. A cracked, faded or swapped insert is easy to spot in photos. The record for this reference reads: unidirectional rotating bezel with black Cerachrom insert.

Dial. Expect buyers to compare the dial with the recorded one (d-Blue gradient (blue to black)) and to ask whether it has ever been replaced or restored.

Polishing. Many steel watches have been polished at least once. Ask how often, because each polish takes metal off the lugs.

Box and papers. Buyers ask for the original box and papers first; keep them together with the watch.

Retail reference. We don't show a list price for this reference, because we only publish one we can confirm from a source we can cite.

Recent movement. Change over the past year: -1.5% over 12 months.

Tips for buyers

  • Match the reference number on the papers (126660) with the watch, and check the 44 mm case.
  • Ask when the calibre 3235 was last serviced, and by whom.
  • Compare the dial with the recorded one: d-Blue gradient (blue to black).
  • Ask the seller how long they have had the watch and why they are selling.
  • Inspect the bezel closely; it should be unidirectional rotating bezel with black Cerachrom insert.
  • Buy with a return period, and use it to get an independent inspection.

Tips for sellers

  • Photograph the dial, bezel, case sides and clasp in daylight.
  • Gather papers, box and service paperwork, including any original parts returned at a service.
  • Skip any cosmetic refinishing; most buyers want the case untouched.
  • Compare each offer with the sold results summarised above.
