Omega Speedmaster Professional vs Rolex Cosmograph Daytona: Current Models and Pre-Owned Generations

The Omega Speedmaster Professional and the Rolex Cosmograph Daytona are the two chronographs most buyers cross-shop: one qualified by NASA in 1965 and worn on the Moon, the other built for racing drivers and now one of the hardest steel Rolex watches to buy at list price. This comparison covers what each brand sells new today, including every variation we could verify as of October 2026 , and the prior generations a buyer can still find pre-owned, from the calibre 1861 Moonwatch to the Zenith-powered Daytona 16520.

Current Omega Speedmaster Professional lineup and variations

Omega's US page for the Moonwatch Professional listed 24 variations on October 14, 2026 , all 42 mm with the calibre 3861 (manual-winding, 50 hours) and a five-arched-link bracelet or a strap. Rolex's own site returned an access error, so the Daytona table is built from dated secondary reports: Rolex's January 1 and June 1, 2026 US increases (Loupe, Luxury Bazaar), Wristcheck's July 2026 guide and Rolex's 2025 and 2026 releases. Treat Daytona prices as reported list prices, not a live read of rolex.com. Two things changed in the last year: Omega added the reverse-panda ceramic-bezel steel and Moonshine gold models in January 2026 , and Rolex added the Rolesium 126502 at Watches and Wonders 2026.

Prior generations: what you can buy pre-owned

Both families have long pre-owned tails, and the dividing lines are different. The Speedmaster changes with its movement: 321 , 861 , 1861 and now 3861 . The Daytona changes with its case and bezel: the manual-wind originals, the Zenith-based 16520 , the in-house 116520 and 116500LN , and today's 126500LN . Pre-owned ranges below are indicative figures from dated dealer guides and market trackers, not guarantees, and they disagree with each other more than modern prices do.

Omega Speedmaster Professional: generations

Rolex Cosmograph Daytona: generations

Design and wearing

The numbers put these two in different classes on the wrist. The Moonwatch is 42 mm and 13.18 mm thick in sapphire, or 13.54 mm in hesalite, at about 138 g with a 47.50 mm lug-to-lug and 20 mm lugs. The Daytona is 40 mm and 11.9 mm thick, so it is two millimetres smaller across and well over a millimetre thinner. The older generations tell the same story in reverse: the calibre 1861 Speedmaster measured 14.3 mm, while the 116500LN and 116520 Daytonas were 12.2 mm, so the 2021 and 2023 refreshes each trimmed the case.

The look splits just as cleanly. The Speedmaster has a stepped dial, a dot-over-90 tachymeter on an anodised aluminium bezel, and, on the hesalite .001, a domed plastic crystal with a solid caseback engraved as the first watch worn on the Moon. The Daytona has a ceramic Cerachrom bezel with a metal ring, the white-dial Panda or black-dial versions of the 126500LN, and a 904L steel bracelet. Water resistance is the practical difference: 50 m on the Speedmaster, 100 m on the Daytona. In 2026 the two met halfway in style, with Omega's steel 310.30.42.50.01.004 adding a black ceramic bezel and Rolex's 126502 adding an anthracite ceramic bezel with a platinum ring. Full model histories sit on our Speedmaster and Daytona pages.

Movement and technology

The Speedmaster's calibre 3861 is a manual-winding chronograph, 27 mm wide, with 26 jewels, a column wheel and vertical clutch, a silicon Si14 balance spring, a Co-Axial escapement and METAS Master Chronometer certification with 15,000 gauss resistance, according to 5DWatches. It beats at 21,600 vph and stores 50 hours. It arrived in January 2021 and replaced the 1861, which itself descended from the 861 that replaced the calibre 321 in 1968. Wearing it means winding it, which many Moonwatch owners count as part of the point.

The Daytona's calibre 4131 is an automatic chronograph at 28,800 vph with a 72-hour power reserve, a Chronergy escapement, Côtes de Genève finishing and a Superlative Chronometer rating of -2/+2 seconds a day (Loupe). It replaced the 4130 in 2023, and that move came with a thinner case. The 4130 was Rolex's first fully in-house Daytona movement, from 2000. Before it, the 16520 used calibre 4030, a modified Zenith El Primero: it was slowed from 36,000 to 28,800 vph and kept about half its original parts, per Wikipedia. The two designs reflect different goals: the Omega keeps a hand-wound, historically correct layout, while the Rolex adds automatic winding and longer reserve. We found no independent timing tests comparing the two current movements, so we do not rank them on accuracy.

Value and collectability

The two families sit on opposite sides of list price. Loupe's April 2026 report put the 126500LN at a market value of $34,783 against a $16,900 list price, a premium of about 106 percent . It also said that premium has compressed roughly 12 percent from its late-2023 peak and that median asking prices were slipping 1 to 2 percent a quarter, so the premium is not a one-way bet. Dealer ranges give the same picture: $31,000 to $38,500 for the 126500LN, $28,000 to $32,000 for the discontinued 116500LN and $20,000 to $24,000 for the 116520 (5DWatches, May 2026).

The Speedmaster is the reverse. A 3861 hesalite lists at $7,800 on Omega's site, while 5DWatches puts the pre-owned range at $4,400 to $5,200 and Majestix at $5,500 to $6,500, so you pay roughly 17 to 44 percent below list for a nearly new one, depending on the source. Majestix adds that a full box and papers adds 10 to 15 percent and missing papers cost $500 to $800. Collector value sits in the extremes: the 105.012 at $30,000 to $80,000 or more, the Silver Snoopy 50th at $25,000 to $32,000, and, on the Daytona side, the Paul Newman dial, whose owner's 6239 sold for $17,752,500 in October 2017. For those stories see our Apollo astronaut watches and Paul Newman watches guides.

Buying new or pre-owned

With the Speedmaster, buying new is a real option. Omega lists 24 variations with US prices, the hesalite sits at $7,800 and the sapphire at $9,000, and the page flagged only one gold variation as unavailable online. A buyer who wants the 2021 movement and a warranty pays the premium over a pre-owned 3861, a gap of roughly $2,600 to $3,400 against the 5DWatches ranges, in return for an unworn watch. A buyer on a budget can step back to the 1861: a 311.30.42.30.01.005 costs $3,500 to $4,500 pre-owned (5DWatches), and Majestix puts it about 25 percent below a new 3861.

With the Daytona, buying new at list is the exception. Wristcheck says waits run past five years at most authorised dealers, and Loupe describes allocations as invitation-only or relationship-gated. Most buyers therefore pay the secondary market: at $31,000 to $38,500 for a 126500LN, that is $14,100 to $21,600 above list. The cheaper entry is an older generation, such as the 116520 at $20,000 to $24,000 or the 116500LN at $28,000 to $32,000. Gold, Rolesor and platinum Daytonas have reported lists of $24,550 (Rolesor) to $84,600 (platinum), but we could not confirm their availability at dealers. Pre-owned vintage needs more care: 5DWatches warns that dial swaps, replacement bezels and aftermarket bracelets are common on vintage Speedmasters, and the same caution applies to a 6263 or 16520. Compare ranges with our best watches under $15,000 guide before you decide.

Which generation to look for

On the Speedmaster side, the cleanest line is 1861 versus 3861 . The 3861 is thinner (13.2 to 13.6 mm against 14.3 mm), certified by METAS and has a redesigned step dial and bracelet. The 1861 is the cheaper route in, at $3,500 to $5,500 depending on crystal. Vintage buyers choose among 105.012 (calibre 321, first with Professional on the dial), 145.012 (last 321) and 145.022 (861, 1968 to 1988). If you want a lunar-era story at a lower cost, the 145.022 is the entry point, although dealer ranges disagree: $8,000 to $18,000 from 5DWatches and $4,000 to $5,000 from Majestix.

On the Daytona side, the choice is between the 116520 (steel bezel, the lower-cost steel Daytona), the 116500LN (ceramic bezel, last of the 4130) and the 126500LN (thinner, 72-hour 4131). The 16520 is a different collector's watch, with a modified Zenith movement and values of $35,000 to $55,000 for clean examples. Original-series 6239 to 6265 watches with ordinary dials were not priced in any source we could verify, so we do not quote a figure. If you want the newest watch, the 2025 and 2026 additions, from the green-dial 126508 to the Rolesium 126502 at $57,800, are priced in gold and platinum territory, and the 126502 is off-catalogue.

Which should you buy?

Myths and mix-ups, corrected

• “The current Moonwatch has the movement that went to the Moon.” No. The lunar-era movements were the 321 and then the 861. The current watch uses the 3861, and the 321 survives only in limited re-editions.
• “Hesalite is a cost-cutting choice.” It is the listed spec on the 310.30.42.50.01.001, the lowest-priced steel Moonwatch on a bracelet at $7,800, against $9,000 for the sapphire version.
• “Every Daytona has a Rolex-made movement.” The 16520 (1988 to 2000) used calibre 4030, a modified Zenith El Primero. Rolex's in-house 4130 arrived in 2000.
• “The Daytona only goes up in price.” Loupe says the 126500LN premium has compressed about 12 percent from its late-2023 peak and median asks are slipping 1 to 2 percent a quarter.
• “The Speedmaster is a dive watch.” The current Moonwatch is rated to 50 m, half the Daytona's 100 m.
