Stepping up in Seiko's range
Titanium end-to-end — case, bracelet, clasp — makes this watch something a full-metal steel equivalent simply cannot replicate in daily use. At 74 grams complete, it sits on the wrist with an absence of weight that takes a day or two to stop noticing. The 8.4mm profile is unusually slim for a 40.2mm watch with this level of water resistance, and it disappears under a cuff without the bracelet bunching. The grey sunray dial works with the matte titanium tones rather than against them, giving the whole watch a coherent, low-contrast character that reads clearly in most light without demanding attention. Hypoallergenic as a matter of material rather than coating, it is a practical choice for anyone whose skin reacts to steel. The bracelet fastens with a dual push-button deployment clasp and accepts micro-adjustment without link removal, which on a lightweight bracelet used daily matters more than it might seem — titanium does not stretch in, and getting the fit right from the start keeps it comfortable across the wrist for years.

Learn more about Seiko
Kintaro Hattori opened a watch and clock shop in Tokyo in 1881, aged twenty-one, and began manufacturing under the name Seikosha — roughly, house of exquisite workmanship — in 1892. The Seiko name appeared on watches from 1924.
The company's significance is that it broke the Swiss monopoly twice. First on precision: Seiko was appointed official timekeeper of the 1964 Tokyo Olympics and built the quartz chronometers and printing timers to do it, and in the 1960s its movements placed highly at the Neuchâtel and Geneva observatory trials against the best Swiss houses.
Then on technology. On Christmas Day 1969 Seiko released the Astron, the world's first quartz wristwatch, accurate to five seconds a month where mechanical watches managed that per day. The consequences for Switzerland were catastrophic — employment in the Swiss industry fell by roughly two-thirds over the following decade. Seiko deliberately did not enforce its quartz patents, allowing the technology to spread.
The same year it produced the 6139, among the first automatic chronographs, and it has since introduced Kinetic, Spring Drive — a hybrid regulating a mechanical mainspring electronically, giving a perfectly gliding seconds hand — and its own dive and field lines.
Seiko remains fully vertically integrated, making its own hairsprings, quartz crystals, and even the Zaratsu-polished cases, at price points from under a hundred pounds upward.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 47mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's.
