The Rolex Sea-Dweller Deepsea (DSSD) is a legendary dive watch, renowned for its robust build, exceptional water resistance, and impressive history. Within the DSSD lineage, subtle yet significant variations exist, most notably between the Mark 1 (MK1) and Mark 2 (MK2) versions. While both models share the same core DNA – impressive depth rating and robust construction – understanding the distinctions between them is crucial for collectors and enthusiasts alike. This article will meticulously explore the key differences between the DSSD MK1 and MK2, addressing specific queries related to the Sea-Dweller 43 (SD43) and its impact on the DSSD market.
The Defining Line: 2018 and the Crown at 6 o'clock
The watershed year separating the DSSD MK1 and MK2 is 2018. This is the year Rolex introduced a significant change: the relocation of the crown from the 3 o'clock position to the 6 o'clock position. This seemingly minor adjustment had significant implications for the watch's design, functionality, and ultimately, its collectible value.
Prior to 2018, all DSSD models featured the crown at 3 o'clock, a design element consistent with many other professional Rolex dive watches. This configuration, while functional, led to some wrist comfort issues for certain users due to the crown’s prominence on the side of the case. The shift to the 6 o'clock position addressed this ergonomic concern, offering a more comfortable fit for many wearers. The placement also allowed for a more symmetrical case design, enhancing the watch's aesthetic appeal. This change marks the definitive difference between the MK1 and MK2. All DSSD models produced from 2018 onwards are considered MK2 versions.
Dial Differences: Subtleties that Speak Volumes
Beyond the crown's position, several subtle yet noticeable differences exist between the MK1 and MK2 dials. These differences, while minor to the untrained eye, are highly sought after by collectors and serve as key identifiers.
* The "1" at 12 o'clock: One of the most prominent differences lies in the font of the numeral "1" at the 12 o'clock position. The MK1 dial features a straight, stick-like "1," while the MK2 dial features a "1" with a small "tick" or serif at the top of the vertical line. This seemingly insignificant detail is a key distinguishing characteristic.
* Depth Rating: While both models boast an impressive 3900m (12,800ft) water resistance, the way it's displayed on the dial differs slightly. The MK1 typically shows "1220m" while the MK2 may use slightly different typography or placement.
* Hang Tags: Another subtle clue lies in the hang tags accompanying the watches. MK1 watches often came with a white hang tag, while subsequent models might vary. However, hang tags are easily lost or replaced, so this is not a reliable sole identifier.
