Sea-Dweller new vs old bezel insert. Preferences?

[DocOc]

Just a couple days ago I purchased a DSSD 126600. Absolutely love the watch. But I just can’t get over the fact that I much preferred the simplicity and clean look of the older bezel insert design found on my 2004 SD 16600 and all of the Submariner models.

I’m wondering what the rationale was for putting all sixty minute markers on the new Sea-Dweller bezel insert.

To do with ISO 6425 standard for a diving watch. Point 1 below:

The standards and features for diver's watches are regulated by the International Organization for Standardization in the ISO 6425 standard; German Industrial Norm DIN 8306 is an equivalent standard. Besides water resistance standards to a minimum of 100 m depth rating ISO 6425 also provides minimum requirements for mechanical diver's watches (quartz and digital watches have slightly differing readability requirements) such as:

Equipped with a diving time indicator (e.g. rotating bezel, digital display, or other). This device shall allow the reading of the diving time with a resolution of 1 min or better over at least 60 min.
The presence of clearly distinguishable minute markings on the watch face.
Adequate readability/visibility at 25 cm (9.8 in) in total darkness.
The presence of an indication that the watch is running in total darkness. This is usually indicated by a running second hand with a luminous tip or tail.
Magnetic resistance. This is tested by 3 exposures to a direct current magnetic field of 4,800 A/m. The watch must keep its accuracy to ± 30 seconds/day as measured before the test despite the magnetic field.
Shock resistance. This is tested by two shocks (one on the 9 o'clock side, and one to the crystal and perpendicular to the face). The shock is usually delivered by a hard plastic hammer mounted as a pendulum, so as to deliver a measured amount of energy, specifically, a 3 kg hammer with an impact velocity of 4.43 m/s. The change in rate allowed is ± 60 seconds/day.
Chemical resistance. This is tested by immersion in a 30 g/l NaCl solution for 24 hours to test its rust resistance. This test water solution has a salinity comparable to normal seawater.
Strap/band solidity. This is tested by applying a force of 200 N (45 lbf) to each spring bar (or attaching point) in opposite directions with no damage to the watch or attachment point.
The presence of an End Of Life (EOL) indicator on battery powered watches.
Testing diving watches for ISO 6425 compliance is voluntary and involves costs, so not every manufacturer present their watches for certification according to this standard.

I prefer the newer, busier look plus not a huge fan of the cyclops - hence my SD4K 116600

Awesome reply!! Thank you so much!

I’m curious though... the regulations stipulate that a diving watch allow for measurement of diving time with a resolution of one minute or better.

But does that mean that one minute increments have to be on the bezel? One could interpret this to mean that such timekeeping could be done on the watch face (although the minute markings on the bezel insert are more pronounced than those on the dial).
