A chronograph is a watch with a built-in stopwatch: a central seconds hand that starts, stops and resets from pushers on the case, with sub-dials that count elapsed minutes and hours. At the top of the market three chronographs define the category. The Rolex Cosmograph Daytona 126500LN is the steel chronograph with the longest waiting list, the Audemars Piguet Royal Oak Chronograph puts a flyback chronograph in the 1972 octagonal case, and the Patek Philippe Nautilus 5980 is the flyback chronograph in gold and two-tone that most collectors consider the most finished of the three. This guide explains how a chronograph works, what separates a column wheel and vertical clutch from cheaper designs, how the three watches compare in size, movement and price, how each wears, and what to check before buying. Bizak & Co. sources all three to order; the chronographs collection lists the references we can seek.

What is a chronograph and how do you read one?
On a standard chronograph the large central seconds hand is the stopwatch, not the running seconds; the running seconds sit in a small sub-dial, usually at 6 or 9. Press the top pusher and the central hand starts sweeping; press it again and it stops; press the bottom pusher and it flies back to zero. The other sub-dials count the elapsed minutes (typically to 30) and hours (typically to 12). A tachymeter scale on the bezel converts an elapsed time over a known distance into a speed, which is what the Daytona's bezel is for. A flyback chronograph adds one function: pressing the reset pusher while the chronograph is running zeroes the hand and restarts it instantly, saving two presses when timing consecutive laps. The Royal Oak Chronograph and the Nautilus 5980 are flybacks; the Daytona is not. All three are certified chronometers or better, and the COSC standard that underlies Rolex's Superlative Chronometer rating is the reference for that accuracy.
Rolex Cosmograph Daytona 126500LN
The 126500LN is the current steel Daytona, introduced in 2023 for the model's 60th anniversary. It is 40 mm in Oystersteel with a black Cerachrom ceramic bezel that now sits in a steel ring, screw-down pushers and crown, 100 m of water resistance and the calibre 4131, which replaced the 4130 of the 116500LN with a Chronergy escapement, Paraflex shock absorbers and 72 hours of power reserve. It uses a column wheel and a vertical clutch, the two features that make a chronograph start without a stutter and run all day without wearing the movement. The dials are black with white sub-dials or white with black sub-dials, the "Panda" that most buyers want. On 21 September 2026 Bizak's sourced catalogue listed the white-dial 126500LN at US$31,619 and the black-dial at US$27,899 brand new, sourced to order. Our 126500LN guide and 116500LN Panda guide go into the reference in depth.
Audemars Piguet Royal Oak Chronograph and Offshore
Audemars Piguet makes the chronograph in two families. The Royal Oak Chronograph is the octagonal-bezel, integrated-bracelet watch of 1972 with a chronograph added; the current 41 mm 26240 uses the in-house calibre 4401, an integrated flyback chronograph with a column wheel, vertical clutch and about 70 hours of reserve, introduced in 2019 to replace the 26320, whose calibre 2385 was a modular chronograph on a thinner base. The 38 mm 26331ST, listed in Bizak's catalogue at US$51,500 on 21 September 2026, carries the earlier 2385 and is the smaller alternative. The Royal Oak Offshore is the 42 mm, heavier-cased version launched in 1993; the current 26238 uses the same calibre 4401, and the catalogue listed the black ceramic 26238CE at US$112,688 on the same date. AP's collection page lists the current chronograph references in each line, and our Royal Oak collecting guide covers what to look for across generations.
Patek Philippe Nautilus 5980
Patek Philippe introduced the 5980 in 2006 for the Nautilus's 30th anniversary and it remains the only chronograph in the Nautilus line apart from the Travel Time 5990. It is 40.5 mm with the calibre CH 28-520 C, an automatic flyback chronograph with a column wheel and vertical clutch that shows elapsed minutes and hours together on a single mono-counter at 6, leaving the dial as clean as a time-only Nautilus. The steel 5980/1A was discontinued in the 2010s and is now a collector's watch; the current line is rose gold (5980/1R), steel and rose gold (5980/1AR) and white gold with a blue dial (5980/60G). On 21 September 2026 Bizak's sourced catalogue listed the 5980/1R at US$236,900, the 5980/1AR at US$132,767, the 5980/60G at US$190,540 and a pre-owned steel 5980/1A-014 with grey dial at US$100,201, all sourced to order. The Patek Philippe Nautilus collection page shows the current versions; our Nautilus 5990 guide covers the Travel Time chronograph that shares its base movement.

Column wheel, vertical clutch and flyback: which mechanisms matter?
Three details separate a chronograph movement built to last from one built to a price. The column wheel is a small castellated wheel that coordinates start, stop and reset; it gives the pushers a crisp, even feel and is more expensive to make than the stamped cam it replaces. The vertical clutch engages the chronograph by friction on the same axis as the running seconds, so the central hand starts without the jump of a horizontal clutch and can be left running indefinitely without wearing the gear teeth or dragging the amplitude down. All three watches above have both. The flyback function is a convenience rather than a mark of quality, but it is a sign of an integrated chronograph designed from the start as one, which is why AP's 4401 and Patek's CH 28-520 have it and the earlier modular 2385 in the Royal Oak did not. A fourth detail is the pusher seal: Rolex and AP screw theirs down, which is why the Daytona is rated to 100 m and the pushers must be unscrewed before use; Patek uses sealed push-pieces that work without unscrewing and still hold 120 m on the 5980.
How does each chronograph wear?
The Daytona is the smallest and the easiest to wear daily: 40 mm, about 12.4 mm thick, on an Oyster bracelet with an Easylink extension, and the screw-down pushers keep the profile tidy. The Royal Oak Chronograph is 41 mm but its integrated bracelet and flat case make it wear larger than the Daytona; the Offshore at 42 mm with its rubber-clad pushers and thicker case is a big watch that suits wrists over 18 cm. The Nautilus 5980 wears the widest of the three because the porthole case stretches from ear to ear; at 40.5 mm it covers as much wrist as a 42 mm round watch, and the gold versions are heavy. For wrists under 17 cm, the Daytona or the 38 mm Royal Oak 26331 are the sensible choices; the 5980 rewards a larger wrist. All three have bracelets that adjust by removing links; only the Daytona has a tool-free extension.
Are luxury chronographs a good investment?
The steel Daytona has been the exception to most rules. It has traded above retail on the secondary market for years because Rolex allocates it to established clients and demand is broad; the gap narrowed in 2024 and 2025 but did not close, and the Panda dial carries the larger premium. The Royal Oak Chronograph in steel has also traded at or above retail for the most requested dials, and the discontinued steel 5980/1A has appreciated far beyond its original list price because Patek stopped making it. Gold and two-tone versions of all three behave more like ordinary gold watches: they trade closer to or below retail and are the value route into the reference. Buy the chronograph you will wear; if resale matters, the steel Daytona is the most liquid chronograph in the world and the one easiest to sell at a known price. The Phillips watch department results are the public record of which discontinued chronographs have appreciated.
Buying a chronograph: what to check
- Pusher action. Start, stop and reset should each need one firm, even press with a clear click; a mushy or double-acting pusher points to a worn column wheel or a bent lever. On a Daytona or Royal Oak, unscrew the pushers first.
- Reset to zero. After reset, the central hand should sit exactly on 12 and the minute and hour counters on zero. A hand that stops a fraction off is a hammer or heart-piece problem that needs a service.
- Running seconds. On a vertical clutch chronograph the running seconds should not stutter when the chronograph engages. Let it run for a minute with the chronograph on and off.
- Bezel. A Daytona's Cerachrom bezel should be unchipped with crisp platinum-filled numerals; a Royal Oak's octagonal bezel should have eight even screw slots, all aligned, and sharp brushed and polished edges.
- Bracelet and clasp. Check for stretch by holding the watch by the clasp; on the 5980, confirm the fold-over clasp locks and that the end links do not rock.
- Card and set. Rolex and Patek both issue papers that cannot be reissued; the difference between a full set and a watch-only chronograph is large on all three references.
- Price against the band. A full-set steel Daytona or Royal Oak Chronograph offered well under the market is the single most reliable warning sign.

Quick answers
What is the difference between a chronograph and a chronometer?
A chronograph is a watch with a stopwatch function operated by pushers. A chronometer is a watch whose movement has passed an accuracy test, usually by COSC. The Daytona, Royal Oak Chronograph and Nautilus 5980 are all chronographs; the Daytona is also a certified chronometer.
Which is better, the Daytona or the Royal Oak Chronograph?
The Daytona is smaller, more water resistant, easier to wear daily and the more liquid on the secondary market. The Royal Oak Chronograph has an integrated flyback movement and the Royal Oak design. They cost similar amounts in steel; the choice is design and wrist size.
Is the Patek Philippe 5980 still made?
Yes, in rose gold (5980/1R), steel and rose gold (5980/1AR) and white gold (5980/60G). The all-steel 5980/1A was discontinued in the 2010s and is now a collector's reference that trades well above its original price.
What does flyback mean on a chronograph?
A flyback chronograph resets and restarts with a single press of the reset pusher while it is running, instead of stop, reset and start. The Royal Oak Chronograph and Nautilus 5980 have it; the Daytona does not.
How much is a Rolex Daytona in 2026?
Bizak's sourced catalogue listed the steel 126500LN at US$27,899 with a black dial and US$31,619 with a white dial brand new on 21 September 2026, above Rolex's list price because of demand. Gold Daytonas were listed pre-owned from about US$45,000.
