As you can see, the 6105-8110 wasn’t the first Seiko diver on the block. The 62MAS was. But objectively, though it was important for Seiko’s own identity, and the democratisation of diving in Asia, it wasn’t an entirely genre bending watch.
But it did spur them on, and in one decade Seiko would have the five prized studs that launched a hundred lines and colour ways, with the 6105-8110 being the most “Seiko” Seiko of them all.
I’ll be honest, I was into the SBDC109 for no more than five minutes when it came out in 2019.
For me, the 62MAS inspired SPB143J was it! It was classy. The anthracite dial said “Yes, I wear an automatic, and yes, I know it looks like John Hamm in a winter coat smoking a Lucky Strike”. There were no bulging sides. No crown guards and no asymmetry. In short, it was nipped and tucked and very capable. It was, and is, the perfect desk-diver watch: a monument to postmodernism.
When this SBDC109 came in for review it took a while to win me over. For those first few hours I expected the chunky watch head to flop around on its hollow end-linked bracelet. It didn’t. It felt smooth and considered.
Intrigued, I tried it on my squadron of Natos. I expected the double-pass ones to add undue height, but you know what? It felt acceptable. A chunky single pass made things better still. But I think you know that the natural, historical and logical home for this watch is a rubber strap. The look, and feel, is off the charts cool. And if you feel like giving the world a couple of YOLO deuces, you could give it some stitched leather shoes. They all work.
The strap change pit stops took seconds because it has drilled lug holes, which equals no bruised inner lugs, or Band Aids round your fingers.
