The Alinghi Red Bull Racing editions come in two distinct versions: the 42 mm, time-only Pelagos FXD (reference 25707KN) and the 43 mm Pelagos FXD Chrono (reference 25807KN). The Chrono adds a chronograph and date, uses a different movement, and had a higher original Swiss price in TUDOR’s 2023 press kit. Both share a black carbon-composite case, matte blue dial, bidirectional 60-minute bezel, 200 m water-resistance rating and approximately 70-hour power reserve.

What the Chrono adds
Elapsed-time timing and a date
The Chrono’s MT5813 movement adds chronograph timing and a date display to the standard hours, minutes and seconds. Its central chronograph seconds hand and 45-minute counter let the wearer measure elapsed time; the small-seconds display is separate. The time-only MT5602 keeps the dial’s timekeeping functions simpler, with hours, minutes and central seconds.
A larger case and a different movement
The Chrono measures 43 mm across, one millimetre larger than the 42 mm time-only FXD. That difference is a stated case diameter, not a guarantee that the Chrono will feel larger or less comfortable on every wrist; these specifications do not establish comparative fit.

#1 Best Overall
- Tudor Pelagos FXD Chronograph Cycling Automatic Black Dial Men's M25827KN-0001
TUDOR describes the MT5813 as developed from the Breitling 01 chronograph calibre, with a TUDOR-developed regulating organ and exclusive finishes. The MT5602 is a self-winding manufacture movement with a bidirectional rotor. TUDOR lists COSC certification, a silicon balance spring and an approximately 70-hour reserve for both calibres. The press kit lists each at 28,800 beats per hour (4 Hz); it gives the MT5602 25 jewels and the MT5813 41 jewels.
What both Alinghi Red Bull Racing editions share
Carbon-composite cases and sailing-inspired details
Both watches combine matte black carbon-composite cases with matte blue dials. TUDOR’s edition page connects the colors and materials to the Alinghi Red Bull Racing AC75 yacht and its blue hull. The dials have red-tipped seconds hands and discreet “Alinghi Red Bull Racing” text on the rehaut; on the Chrono, red details also pick out the counters.
Rank #2
- Featuring a Blue Band, Black Case, Scratch Resistant Sapphire Crystal
- Display Type: Analog
- Item Shape: Round
TUDOR says it began a long-term partnership with Alinghi Red Bull Racing in 2022. The watches were announced on June 29, 2023, according to TUDOR Japan’s announcement.
Bezel, water resistance and strap
Each model has a bidirectional 60-minute titanium bezel with a carbon-composite insert. TUDOR specifies water resistance of 200 m (660 ft) for both; that is the manufacturer’s rating, not a claim of independent testing.
Rank #3
- Tudor Pelagos Chronometer Black Dial Titanium Men's Watch M25600TN-0001
Both editions are supplied on a 22 mm, single-piece jacquard-woven fabric strap in “Team Blue” with red touches. TUDOR identifies Julien Faure, in the St-Étienne region of France, as the maker and describes the strap as having a titanium D buckle and hook-and-loop closure. The published specifications do not establish hands-on comfort or durability, or confirm compatibility of particular aftermarket straps.

- Choose the FXD, reference 25707KN, if you want a time-only display, prefer the smaller stated case diameter, or are comparing the two using their original Swiss press-kit prices. Its launch-era Swiss figure was CHF 3,500 including VAT.
- Choose the FXD Chrono, reference 25807KN, if you will use a chronograph and date and prefer those functions despite the 43 mm case and higher original Swiss press-kit price of CHF 4,850 including VAT.
Those Swiss amounts are not current-price guidance. TUDOR’s current Pelagos family page can help locate the family and its official retailer locator, but current prices, regional availability and stock for these specific references are not established here. Confirm the exact reference with a retailer; do not confuse reference 25807KN with the separate Pelagos FXD Chrono Cycling Edition.
