Ulysse Nardin Executive Ref. 243-00 Review – A Collector’s Sleeper
The Ulysse Nardin Executive ref. 243-00 is a watch that doesn’t scream for attention – it earns it. Launched in the late 1990s, this 40mm stainless steel automatic with a clean date complication represents the brand’s pivot from marine chronometers to contemporary luxury sports watches. It’s the kind of piece that auction house specialists and seasoned collectors nod at knowingly, while the hype crowd scrolls past. For the young collector who values substance over social media noise, the Executive 243-00 is a quiet power move.
This isn’t a watch that relies on celebrity endorsements or limited-edition frenzy. Its appeal is rooted in Ulysse Nardin’s horological credibility – a brand that has been making precision instruments since 1846. The Executive line, introduced in the 1990s, was designed to bridge the gap between the brand’s nautical heritage and a modern, everyday-wearable aesthetic. The ref. 243-00, with its clean dial, robust UN-26 movement, and 100m water resistance, became the archetype of that philosophy.
Today, the 243-00 is a sleeper on the pre-owned market. It offers the build quality of a Swiss luxury watch at a fraction of the price of a Rolex Explorer or Omega Aqua Terra. For the trust-fund-baby buyer who wants to look like they know watches – not just wear them – this is a compelling entry point into independent horology.
Manufacture History
Ulysse Nardin was founded in 1846 in Le Locle, Switzerland, and quickly became a leading manufacturer of marine chronometers. The brand’s precision instruments were used by navies around the world, earning a reputation for accuracy that few could match. In the 1990s, under the leadership of Rolf Schnyder, Ulysse Nardin reinvented itself with bold designs and in-house movements, while still honoring its nautical roots. The Executive line, launched in that era, became the everyday face of the brand – robust, clean, and unmistakably Ulysse Nardin.
Movement
The ref. 243-00 is powered by the UN-26 caliber, a modified ETA 2892-A2. This automatic movement beats at 28,800 vph, offers a 42-hour power reserve, and features 21 jewels. It’s a workhorse – reliable, easy to service, and accurate enough for daily wear. While not COSC-certified, the UN-26 is finished with Ulysse Nardin’s signature perlage and blued screws, giving it a level of decoration that exceeds the base ETA. The date complication is quick-set and operates smoothly. For the purist, the lack of an in-house movement might be a sticking point, but for the practical collector, the UN-26 is a proven platform that keeps service costs low.

Wrist Feel
On the wrist, the Executive 243-00 is a masterclass in balance. The 40mm case wears closer to 39mm thanks to the short, curved lugs, and the 11.5mm thickness slides effortlessly under a shirt cuff. The weight is substantial without being heavy – about 90 grams on the leather strap – giving it a reassuring presence. The polished bezel and brushed case sides catch light subtly, while the signed crown screws down with a satisfying click. It’s the kind of watch you forget you’re wearing until you glance down and remember why you bought it.
The leather strap is supple out of the box, though some collectors swap it for a rubber or NATO for a sportier vibe. The deployant clasp is well-engineered, with a smooth action and no sharp edges. Overall, the 243-00 feels like a tool watch dressed in a suit – capable, comfortable, and quietly confident.
Accuracy
In real-world use, the UN-26 movement typically runs within +5 to +10 seconds per day. It’s not COSC-certified, but most examples I’ve handled settle around +7 s/d after a full wind. The movement is robust and holds its rate well through daily wear, though it can be sensitive to magnetism – a common trait for ETA-based calibers. A quick demagnetization every year or two keeps it on track.
Occasions
The Executive 243-00 is a true GADA (go-anywhere, do-anything) watch. It works with a suit, jeans, or swim trunks – the 100m water resistance and screw-down crown make it pool-safe. It’s not a dedicated dress watch, but its clean dial and moderate size allow it to pass in formal settings. For travel, the date complication is a practical bonus.
Wrist Presence
3/5 – Understated but unmistakably quality. It doesn’t shout, but those who know will nod.
Reference Variants
- 243-00 – Black dial, leather strap. The standard production model.
- 243-00/40 – Silver dial, leather strap. Less common, with a brighter, more formal look.

The Executive line includes the Dual Time (ref. 243-55), Chronograph (ref. 243-66), and Skeleton (ref. 243-88). All share the same case architecture and design language.
Other Notable Models by Ulysse Nardin
- Marine Torpilleur – A dressier take on the brand’s nautical heritage.
- Freak X – A bold, avant-garde piece with a flying carousel movement.
- Diver Net – A modern, sustainable dive watch made from recycled materials.
Similar Watches
- Omega Aqua Terra 150M – Similar size, clean dial, and versatile daily wearer with a strong brand pedigree.
- Rolex Explorer I (ref. 214270) – The go-to 39mm sports watch with a date-less dial, but the Executive offers a date and a more independent spirit.
- IWC Mark XVIII – Pilot’s watch with a similar tool-watch ethos, though the Executive has a more refined finish.
Homages
- Seiko SNXS79 – A 37mm automatic with a similar clean dial and date, but at a fraction of the price – a great entry-level alternative.
- Tissot Gentleman Powermatic 80 – Offers a similar 40mm size, date, and 100m water resistance with a modern movement, though lacks the Ulysse Nardin heritage.
Investment Value
The original MSRP of the 243-00 was around $2,500. Today, a pre-owned example in good condition ranges from $1,800 to $2,800, with retail prices for new old stock around $3,200. The trend is stable – it’s not appreciating rapidly, but it’s not losing value either. For the collector, it’s a solid long-term hold. Auction history is minimal; this model rarely appears at high-profile sales, which actually adds to its under-the-radar appeal.
Service Interval
Ulysse Nardin recommends service every 5 years. A full service at an authorized center costs around $800, but independent watchmakers can do it for about $600 due to the ETA base. Parts are readily available, making this a low-maintenance luxury watch.
Pros and Cons
Pros: Clean, timeless design; robust ETA-based movement; 100m water resistance; strong brand heritage.
Cons: Not an in-house movement; lume is adequate but not industry-leading; leather strap can feel stiff initially; limited aftermarket parts support compared to Rolex or Omega.
Final Verdict
The Ulysse Nardin Executive ref. 243-00 is a quiet masterpiece of the late-’90s luxury sports watch era. It offers the build quality and heritage of a storied independent brand without the hype or premium. For the young collector who values substance over status, this is a watch that will age gracefully – both on the wrist and in the collection.
