King Seiko KSK 6L Adds Slimline Calibre to Seiko’s Stylish Collection

In my personal opinion one of the most exciting launches of 2022 was the reintroduction of the King Seiko brand as one of Seiko’s core collections. Across the year we saw a handful of additional King Seiko releases such as the KSK 1965 Re-Creation Limited Edition. The newest addition to the line-up is the Seiko King Seiko KSK 6L, which introduces Seiko’s 6L series of movements to the collection for the first time.

Aesthetically the case of the King Seiko KSK 6L is very similar to the other modern interpretations with a round shape, strong lugs and facetted angles. However, to accommodate for the 6L35 automatic movement, the case is slightly broader at 38.6mm in diameter. That’s in comparison to the 37mm and 38.2mm editions that have come before. However, while it’s broader it’s also thinner with a thickness of 10.7mm as opposed to 12.1mm or 11.4mm.

There are two colourways available which are pretty much explained by their names: Cool Black and Sunray Silver. They’re very classical, classy colours that give the watch a mature elegance. The same can be said of the understated, facetted hands and applied hour markers. A particularly nice touch is that they’ve gone to the effort of colour matching the date discs to create a cohesive appearance.

As mentioned, the King Seiko KSK powered by 6L35 automatic movement, marking the first time a 6L movement has been used in a mainline King Seiko (it has appeared in limited edition versions previously). 6L is Seiko’s slimline range of movements, which is how they’ve been able to make the model slimmer even though it has a date complication. Specs-wise it has a 45-hour power reserve and an accuracy of -10/+15 seconds per day.

Ultimately, I don’t think this is the most revolutionary update to the King Seiko. On a style front it doesn’t add anything we haven’t seen before and structurally it remains in the same ballpark despite minor differences in size. At least the movement is a notable upgrade, justifying the increased £2,900 price tag. Plus, giving collectors more options to choose from is always beneficial.
