The Ulysse Nardin Marine Regatta’s defining feature is a countdown that turns itself into a race timer: set one to ten minutes, and at zero the central seconds hand reverses direction automatically to measure elapsed race time. The 44 mm steel watch, reference 1553-155-3/43, was launched in 2017. Its mechanism and specifications are documented by the GPHG and the Fondation de la Haute Horlogerie; those records do not establish personal wear impressions.
How does the Ulysse Nardin Marine Regatta countdown work?
The watch combines a pre-start countdown with elapsed race timing. Rather than requiring the wearer to start a separate chronograph at the starting signal, the central seconds hand changes direction automatically when the countdown reaches zero.
- Set the countdown: Use the pusher at 10 o’clock to set the countdown hand for a duration from one to ten minutes. The hand indicates the remaining minutes against a yellow scale marked from zero to ten.
- Count down to the start: Once activated, the countdown hand travels counterclockwise. The central seconds hand also moves counterclockwise, showing the seconds remaining before the start.
- Time the race: At zero, the central seconds hand automatically reverses and runs clockwise to record elapsed race time. The subdial at six o’clock displays elapsed hours and minutes.
This automatic changeover is the Marine Regatta’s key distinction: the countdown and race timing form one sequence. The documented setting range is one to ten minutes, not an unrestricted countdown. Both the GPHG description and the FHH account describe the central hand’s reversal.
What is the reference number for the Ulysse Nardin Marine Regatta?
The reference is 1553-155-3/43. GPHG identifies the model as launched in 2017. Its technical listing categorizes the functions as hours, minutes, seconds, date, chronograph, flyback chronograph and split-second chronograph. For a user trying to understand the watch’s signature operation, the specific regatta countdown-to-timing transition is the more informative description.

How big is the Marine Regatta?
GPHG lists a stainless-steel case measuring 44 mm in diameter and 14.9 mm thick, with 100 m water resistance. These are published specifications, not a substitute for trying the watch on; the available sources do not establish how it fits or wears on a particular wrist.
What movement and power reserve does it have?
The Marine Regatta uses Ulysse Nardin caliber UN-155, a self-winding mechanical movement with a stated 72-hour power reserve and silicon escapement. GPHG lists 650 movement components; FHH also gives the 650-component figure. The power-reserve figure appears in both institutions’ descriptions.

What dial and strap options are documented?
GPHG and FHH describe ocean-blue and sea-foam dial options. GPHG specifies a rubber strap with a folding buckle. The cited records identify these configurations but do not establish the full range of market variants or how the strap feels in use.
Is the Ulysse Nardin Marine Regatta still available?
The cited institutional listings establish the watch’s identity and 2017 launch, but they do not confirm current manufacturer availability, present-day retail stock, or resale pricing. GPHG lists CHF 15,900 excluding VAT on its 2017 listing; treat that as launch-era price context, not a current quotation or estimate of secondary-market value. For a search, use the complete reference, 1553-155-3/43, and verify the exact reference, condition, seller and current price directly with any retailer or dealer.

What should a hands-on assessment establish?
Published specifications explain what the mechanism is designed to do, but they cannot answer practical questions such as how easily the countdown is set, how clearly the dial reads in different light, how the pushers feel, or how the case and strap sit on the wrist. Those points require direct observation. A useful in-person check is to set a countdown, watch the seconds hand reverse at zero, and assess the display and fit for yourself.
