Do I have to buy the whole build, or can I buy parts separately?

Every item in the 1908 Lineup is sold individually. Buy the complete matched build — case, dial, hands, crown, chapter ring, bracelet — or just the pieces you need for an existing project. The collection is arranged as two ready-matched builds so you don't have to guess which parts agree.

What's the difference between the steel and yellow gold builds?

The steel build uses a polished 316L stainless steel case with a silver-index dial, silver Breguet hands, and a silver crown, chapter ring, and bracelet. The yellow gold build uses the same 316L case finished in durable PVD yellow gold, paired with a gold-index dial, gold hands, and gold crown, chapter ring, and bracelet. The yellow gold is a PVD coating, not solid gold — it carries the look with far better wear resistance and a far lower price.

What does a complete watch need beyond this collection?

The case ships as a case body — case, caseback, bezel, and double-dome sapphire crystal. The 1908 Lineup adds the matching dial, hands, crown, chapter ring, and bracelet — so the only part you still need to add is an NH movement (sold separately). New to this?

Why does the build include an SKX013 chapter ring?

Every Ultra Thin Edition case is built around the SKX013 chapter ring — it is not optional, it is the chapter ring the architecture is designed for. This collection includes the mirror-polished version finish-matched to each build: silver for the steel build, gold for the yellow gold build. It seats between the dial edge and the case, completing the dress-watch look.

Is the 1908 case really GMT-ready?

Yes. Both 1908 cases are engineered for the Seiko NH34 GMT movement, as well as NH35, NH36, and NH38. The NH34 is slightly taller than the others, so the case uses a double-dome sapphire crystal to give the hands clearance. Note that NH34 requires a GMT dial with a wider 2.70mm centre hole — a standard NH35 dial will not fit the NH34.

How thick is the 1908 case, and what wrist does it suit?

The 1908 36mm case is 10.75mm thick including crystal and caseback — genuinely slim for a dress case, and slimmer still for one that takes a GMT movement. At 36mm with a 20mm lug width, it sits comfortably on most wrists from roughly 6.0 to 7.5 inches, and the slim profile lets it slide under a cuff cleanly.

Can I use my own dial and hands instead of the 1908 set?

Yes. The 1908 case accepts any standard 28.5mm dial and any NH-compatible handset. The matched 1908 dial and Sword Breguet hands are the intended dress pairing, but the case is fully compatible with the wider Ultra Thin Edition parts range if you want to build something different.

What strap or bracelet fits this case?

The 1908 case uses a 20mm lug width, so any standard 20mm strap, NATO, or bracelet fits. The matched choice is the Settimo Bracelet, which tapers from 20mm to 16mm in solid steel with a butterfly deployment clasp — drawn specifically for this case's dress proportions.

1908 Lineup

A complete dress build — not a parts hunt. The 1908 Lineup is the one collection where every piece is already matched for you. Case, dial, hands, crown, chapter ring, and bracelet — designed as a set, finished to agree, offered in two metals. Pick steel or yellow gold and the whole build comes together without a single mismatched component.

At its heart is the 1908 36mm case from our Ultra Thin Edition — a semi-fluted dress case just 10.75mm thick, with a double-dome sapphire crystal and a polished finish that belongs under a cuff. It is fully NH34 GMT-ready, so a sub-11mm dress watch can still run a true GMT complication. Everything else in this collection was drawn around it.

Steel or yellow gold?

Want a versatile everyday dress watch? The steel build — bright polished 316L, silver dial, silver Breguet hands. Pairs with everything.
Want maximum formal presence? The yellow gold build — PVD gold case, gold-index dial, gold hands. A statement piece for the dress-watch lover.
Going GMT? Either case takes the Seiko NH34 GMT movement out of the box — no compromise on slimness.
Building for someone else? A matched build is the safe gift — every part already agrees, nothing to second-guess.

The two builds, part by part

Component	Steel build	Yellow gold build
Case	1908 36mm — polished 316L steel	1908 36mm — PVD yellow gold
Dial	1908 Dial — silver indices, no date	1908 Dial — yellow gold indices, no date
Hands	1908 Sword Breguet — polished silver	1908 Sword Breguet — polished yellow gold
Crown	SKX Crown II, 1908 Presage style — 6mm silver	SKX Crown II, 1908 Presage style — 6mm yellow gold
Chapter ring	SKX013 Chapter Ring — mirror-polished silver	SKX013 Chapter Ring — mirror-polished gold
Bracelet	Settimo Bracelet 20/16mm — silver	Settimo Bracelet 20/16mm — yellow gold

Each part is sold individually — buy the full set or just the pieces you need. The only thing not in this collection is the NH movement, which every build also requires (sold separately). Both cases are NH34, NH35, NH36, and NH38 compatible.

Why it works as a set

The case. The 1908 36mm is a semi-fluted dress case — half-fluted bezel with a polished domed top — built on our Ultra Thin Edition architecture. Total thickness is 10.75mm including the double-dome sapphire crystal and solid caseback. The steel version is polished 316L stainless steel; the yellow gold version is a durable PVD gold coating over the same 316L base, sold as its own product.

The dial and hands. The 1908 dial pairs applied indices on a clean ground with a faceted baton layout — classic dress-watch legibility. The Sword Breguet handset is the intended partner: a Breguet-style hour hand with faceted, mirror-polished sword minute and second hands. Silver-on-silver or gold-on-gold, the dial and hands are finished to match.

The crown, chapter ring, and bracelet. The SKX Crown II is a 6mm 1908 Presage-style crown, finished to match the case metal. Every Ultra Thin Edition build needs an SKX013 chapter ring, and this collection includes the matched mirror-polished one — silver for the steel build, gold for the yellow gold build. The Settimo bracelet tapers 20mm to 16mm in solid steel with a butterfly deployment clasp — the dress bracelet drawn for this case. Prefer a strap? The 20mm lug width takes any standard 20mm strap or NATO.

GMT-ready. Both 1908 cases accept the Seiko NH34 GMT movement. Achieving a true GMT in a sub-11mm dress case is the engineering point of the line — the double-dome crystal provides the hand clearance the taller NH34 needs. Note that NH34 requires a GMT dial with a 2.7mm centre hole; a standard NH35 dial will not fit the NH34.

Two metals, one design language. Build it as a set, or take the pieces you need.
