To pick a seiko mod style, start from how you will wear it: an integrated bracelet for dressed-up everyday wear, a chronograph for a racing feel, a GMT for travel, a dive style for sport, a fluted bezel for a classic look. At Modus each style has its own collection, at €295 in the catalogue (€329 for the skeleton, €339 for the GMT), with a Seiko NH35, NH34, NH38, NH70 or VK63 movement, and from €349 in the configurator.
These styles come from watches that buyers name outright: the Nautilus by Patek Philippe and the Royal Oak by Audemars Piguet for the integrated bracelet, the Daytona by Rolex for the racing chronograph, the GMT-Master by Rolex for the dual time zone, the Submariner by Rolex for the dive style, the Datejust by Rolex for the fluted bezel. We name them here to describe a style. A seiko mod inspired by one of them is not that watch: it carries the Modus name, its movement comes from Seiko Instruments, and its price, construction and finishing are of a different kind.

Integrated bracelet: the 1970s look
An integrated bracelet has no lugs: it leaves the case directly. The style was popularised by the Royal Oak by Audemars Piguet, presented in 1972 with its octagonal bezel, and by the Nautilus by Patek Philippe, presented in 1976. Both were drawn by Gérald Genta. At Modus, PRISM has a 42 mm case that is 13 mm thick, in blue or in rose gold with an open-heart dial; ORBIT takes its cue from the octagonal bezel with visible screws, as an automatic, a chronograph or a skeleton. For the style's history and practical limits, read integrated bracelet watches: what they are and how to choose.
Racing chronograph: three subdials and a tachymeter
The racing chronograph owes its look to the Daytona by Rolex, launched in 1963 with three subdials and a tachymeter bezel, and to the Speedmaster by Omega, born in the 1950s. "Panda" dials, white with black subdials, or "reverse panda" are its signature. INTERVAL offers six versions, COSMOS two. The movement is a VK63: the chronograph is mechanical, the time is kept by a quartz module, and the watch runs on a battery, about 3 years in normal use. It is not an automatic.
GMT: two time zones at a glance
The GMT-Master by Rolex, introduced in 1954 for airline crews, set the template: a fourth hand that makes a full turn in 24 hours and a bezel graduated over 24 hours, often in two colours. That is where the bezel nicknames heard everywhere come from, such as Pepsi (blue and red) or Batman (blue and black). MERIDIAN offers six versions on an NH34, whose GMT hand can be set independently of the local time. See how a GMT watch works.
Dive style: rotating bezel and luminous markers
The Submariner by Rolex, which appeared in the 1950s, fixed the codes of the dive watch: rotating graduated bezel, large luminous markers, steel bracelet. DEPTH takes its cue from them in six versions, in black, blue, two-tone, gold or with vanilla markers. An important point: this is a dive style, not a dive watch. Modus states 5 ATM, which rules out swimming as well as diving.
Fluted bezel: the classic with a date
The fluted bezel and five-row bracelet are the marks of the Datejust by Rolex, launched in 1945 with a date in a window, and of the Day-Date by Rolex, which appeared in 1956 with the day spelled out in full. AXIS takes its cue from that silhouette in two versions, including a 36 mm Day & Date that suits slim wrists.
Sport with a rubber strap
One last style comes from the Aquanaut by Patek Philippe, launched in the late 1990s: a rounded octagonal case and an embossed rubber strap. ATLAS offers three versions, with a brown, khaki or black dial, on an NH35, at €295.
Five questions to decide
- Where will you wear it? Office and evenings: integrated bracelet or fluted bezel. Weekends and travel: GMT, dive style or ATLAS. For a sporty feel: chronograph.
- What is your wrist size? For a 15 to 16 cm wrist, 36 to 39 mm is the usual advice: look at the 36 mm AXIS Day & Date. See also the watch size guide. A 42 mm integrated bracelet looks wider than its diameter.
- Automatic or battery? Every style is automatic except the chronograph, which is mecha-quartz and needs a battery roughly every 3 years.
- Do you need a second time zone? If so, MERIDIAN is the only GMT collection, at €339.
- Do you want your own combination? The configurator lets you choose case, dial, hands and bracelet from €349.
What each style will not give you
A seiko mod inspired by a classic gives you neither the movement, nor the construction, nor the name of the watch that inspired it. It gives you a style, a well-known movement that can be serviced almost anywhere, and a starting price of €295. The dial, bezel, crown and case back of our watches carry no other brand's name or logo: only the Modus Horlogerie name appears.

Frequently asked questions
Which seiko mod style should I choose for a first purchase?
The most versatile is an automatic three-hander with a date on an NH35: dive style (DEPTH), fluted bezel (AXIS) or integrated bracelet (PRISM), at €295. Choose the chronograph or the GMT only if you will use their functions.
Which seiko mod suits a small wrist?
Aim for 36 to 40 mm (the usual advice for a 15 to 16 cm wrist is 36 to 39 mm). The AXIS Day & Date is 36 mm; the black DEPTH, the INTERVAL panda, the MERIDIAN with the black and grey bezel and the FIELD are 40 mm according to their product pages. A 42 mm integrated bracelet such as PRISM looks wider than its diameter.
Is a seiko mod chronograph automatic?
No. The VK63 is a mecha-quartz: the chronograph is mechanical, the time comes from a quartz module and the watch runs on a battery, about 3 years in normal use. All other Modus collections are automatic.
Can I swim with a dive-style seiko mod?
No. A Modus dive-style seiko mod is rated 5 ATM: rain and splashes, not swimming or diving. For swimming you need a watch rated 10 ATM or more.
How much does a seiko mod cost depending on the style?
At Modus on 17 October 2026: €295 for most styles, €329 for the ORBIT skeleton, €339 for the MERIDIAN GMT, and from €349 in the configurator. Delivery is free.
Is a seiko mod inspired by a famous brand?
It takes inspiration from a style, such as the integrated bracelet or the fluted bezel, without carrying another brand's name or logo. Modus watches carry the Modus Horlogerie name, and Modus is not affiliated with any of those brands.
Can I build my own seiko mod?
Yes, in the configurator: case, dial, hands and bracelet, from €349. Options (dial logo, engraving, GMT hand) are added to the base price.
