Paulin’s current catalog lists each with a 35 mm quartz or manual movement, or a 39 mm automatic. Current UK list prices are £450, £990 and £900 respectively; prices and stock can change.
What distinguishes the Modul D from the Modul E?
The main difference is the dial finish and color scheme, not the movement range. Paulin’s current product pages identify the D as lacquer and the E as brushed rhodium. The detailed colors below were reported in Monochrome Watches’ launch coverage on 18 October 2024, so treat them as launch-era descriptions rather than a guarantee of every current listing.
- Modul D: black lacquer on brass, with blue, white and red hands, white Arabic numerals and yellow indices.
- Modul E: brushed rhodium, with orange and blue hands, blue Arabic numerals and orange indices.
Both are time-only designs. Current catalog entries offer the same three movement and case-size configurations for either dial treatment.
Current Paulin Modul D and E options
Paulin’s current catalog lists the following UK configurations and prices. These are listed prices, not a guarantee of availability or a price that will remain unchanged.

#1 Best Overall
- AN ICON SINCE 1989 — THE WORLD'S MOST POPULAR DIGITAL WATCH — Introduced in June 1989 as a successor to the F-87W, the F-91W is popular for its low price, long battery life, and iconic design. As of 2026, production of the watch has reached 100 million units, making it the most sold watch in the world. A timeless design, unchanged since launch, that has earned a global cult following across generations.
- FEATHERLIGHT & SLIM — Urethane resin is employed for the case and band, and the module features a reduced number of components — every element of construction was reconsidered to secure high quality at an affordable price, resulting in a global hit watch that offers both affordability and long-lasting reliability. The case measures 38.2 × 35.2 × 8.5mm and weighs just 21 grams — barely noticeable on the wrist.
- 1/100-SECOND STOPWATCH WITH SPLIT TIME — The 1/100-second stopwatch covers elapsed time, split time, and 1st-2nd place timing up to 59'59.99" — precise enough for sports, training, cooking, and any timed activity. Handy features for day-to-day life also include a daily alarm, water resistance, and LED light functions.
- DAILY ALARM | HOURLY CHIME | AUTO-CALENDAR | LED LIGHT — Module 593 delivers functions for a daily alarm, chronograph/stopwatch, annual calendar, and hourly chime, with selectable 12 or 24-hour format. The auto-calendar and LED backlight round out a complete, practical feature set in a package that fits any wrist from 145 to 200mm.
- 7-YEAR BATTERY | MODULE 593 | 18MM LUG WIDTH — Powered by a CR2016 battery with an approximate 7-year life — often lasting 10 or more years in practice. The F-91W has an 18mm lug width, meaning standard 18mm NATO straps fit directly without any modification — making it one of the most customizable and mod-friendly watches available at any price point.
| Configuration | Movement | Case diameter | Lug to lug | Strap width | Current UK list price |
|---|---|---|---|---|---|
| Quartz | ETA F06.105 | 35 mm | 40 mm | 18 mm | £450 |
| Manual | ETA 7001 | 35 mm | 40 mm | 18 mm | £990 |
| Automatic | La Joux-Perret G101 | 39 mm | 45 mm | 20 mm | £900 |
The listed size and strap-width differences are practical selection points: the two 35 mm models use an 18 mm strap, while the 39 mm automatic uses a 20 mm strap. Check the specific listing before ordering a replacement strap.
How to choose between the 35 mm manual and 39 mm automatic
Choose the 35 mm manual for a smaller case and hand-wound movement
The manual Modul is 35 mm across, has a 40 mm lug-to-lug measurement and takes an 18 mm strap. Its ETA 7001 movement is hand-wound. Monochrome Watches reported approximately 45 hours of power reserve at the 2024 launch; that is a launch-era specification, not a current measurement independently established here.
Rank #2
- Sport watch with blue dial border, rectangular dial window, perpetual calendar functions, and alarm feature
- 26 mm resin case with mineral dial window
- Quartz movement with digital display
- Ribbed resin band with buckle closure
- Water resistant
Choose the 39 mm automatic for a larger case and automatic movement
The automatic is 39 mm across, measures 45 mm lug to lug and takes a 20 mm strap. It uses the La Joux-Perret G101. Monochrome Watches reported a 68-hour power reserve at launch in 2024; that figure is likewise launch-era information.
Consider the quartz option too
The 35 mm quartz version uses the ETA F06.105 and shares the 40 mm lug-to-lug and 18 mm strap width of the manual model. At the current listed UK price of £450, it is the lowest-priced configuration in the catalog, though the quartz movement may not suit someone specifically seeking a mechanical watch.
Rank #3
- COMPACT SQUARE DIGITAL — A petit square digital watch that's perfect for the feminine wrist, the LA-20WH brings Casio's proven digital reliability into a compact, colorful package. The resin case measures 34.5 × 30.4 × 8.6mm and weighs just 16 grams — featherlight and slim enough to wear all day without fatigue, fitting wrists of virtually any size.
- LED ILLUMINATOR FOR EASY LOW-LIGHT READING — The LED light activates at the press of a button, illuminating the display clearly in low-light conditions — from dimly lit rooms to outdoor evenings. Simple, instant, and practical for daily use without draining the battery unnecessarily.
- 1/100-SECOND STOPWATCH WITH SPLIT TIME — The 1/100-second stopwatch covers elapsed time, split time, and 1st-2nd place timing up to 59'59.99" — precise enough for sports, fitness, cooking, and any activity where accurate timing matters. Clean and easy to operate with the side-mounted mode and function buttons.
- DAILY ALARM | HOURLY TIME SIGNAL | FULL AUTO-CALENDAR — Features a daily alarm, hourly time signal, and full auto-calendar with selectable 12/24-hour format, accurate to ±30 seconds per month. Powered by a reliable Japanese quartz movement and a day-date display that shows the hour, minute, second, PM indicator, date, and day at all times.
- 5-YEAR BATTERY | WATER RESISTANT | AVAILABLE IN MULTIPLE COLORS — Powered by a CR1616 battery with an approximate 5-year life. Water resistant for everyday use — suitable for splashes and rain, though not intended for swimming or prolonged submersion. Available in a wide range of colorways including Pink, Blue, Grey, Black, Black/Blue, Black/Orange, and Black/Purple — a color for every personality and style.
Crystal, water resistance and other listed specifications
Specifications have changed between launch coverage and the current product pages. Monochrome Watches’ 18 October 2024 article described the collection with Hesalite crystal. Paulin’s current product pages specify a machined sapphire box crystal; the current Modul D automatic page calls it a sapphire box-section lens. These are dated descriptions, not one timeless specification.
Paulin’s current pages list 5 ATM water resistance. The current Modul D automatic page additionally specifies a 316L stainless-steel case, 9.7 mm thickness including the crystal, and a 24-month warranty. Those additional details are stated for that automatic product page and should not be assumed to cover every configuration unless its listing confirms them.
What the launch prices were—and why they differ
At the collection’s 2024 launch, reported in Monochrome Watches’ article dated 18 October 2024, the 35 mm hand-wound model was priced at GBP 825 excluding VAT and GBP 990 including VAT. The 39 mm automatic was GBP 750 excluding VAT and GBP 900 including VAT. Those are historical launch prices. Paulin’s current catalog lists £990 for manual and £900 for automatic, while adding the £450 quartz configuration; check the official listing for the price applicable when you buy.
