The Rolex Submariner 124060 is the newer no-date model: a 41 mm Oystersteel case with caliber 3230 and about 70 hours of power reserve, replacing the 40 mm 114060 and its caliber 3130 with about 48 hours. The look is nearly identical, the movement is the real upgrade, and the case is only slightly larger on the wrist. Bizak & Co. is a sourcing desk, not an authorised Rolex retailer, so every watch mentioned here is sourced on request rather than held in stock.

What is the main difference between the 114060 and the 124060?
The headline change is the movement, followed by the move from a 40 mm to a 41 mm case. The 114060 uses the Rolex caliber 3130 with a power reserve of approximately 48 hours. The 124060, introduced in 2020, uses caliber 3230, which Rolex rates at approximately 70 hours and which adds the Chronergy escapement. Both are no-date Submariners with a black dial, a black Cerachrom bezel and an Oyster bracelet with the Glidelock extension.
How do the specifications compare?
On paper the two watches share most of their DNA. The table lists the figures Rolex published for each reference.
| Feature | Submariner 114060 | Submariner 124060 |
|---|---|---|
| Case diameter | 40 mm Oystersteel | 41 mm Oystersteel |
| Movement | Caliber 3130 | Caliber 3230 |
| Power reserve | Approximately 48 hours | Approximately 70 hours |
| Rated precision | -4/+6 seconds per day (COSC, uncased movement) on watches from 2012 to about 2015; -2/+2 seconds per day after casing on later watches | -2/+2 seconds per day, after casing |
| Bezel | Black Cerachrom, unidirectional | Black Cerachrom, unidirectional |
| Bracelet and clasp | Oyster with Glidelock extension | Oyster with Glidelock extension |
| Glidelock adjustment | 10 notches of about 2 mm | 10 notches of about 2 mm |
| Water resistance | 300 m | 300 m |
Is a 41 mm Submariner really bigger than a 40 mm one?
Not by much. The one-millimetre jump is the figure on the spec sheet, but dealers who have measured both report a gap of well under a millimetre in practice, and that reading is a dealer measurement rather than a Rolex figure. Reports also describe the 124060 lugs as slightly slimmer and the crown guards as less chunky than the broad "Super Case" shape of the 114060, which gives the newer watch a crisper profile without adding much visual size. If you are choosing on wrist presence alone, try both on, because lug-to-lug and thickness can matter more than the diameter number.
What changed in the movement?
The 124060 gains a newer calibre family, and the practical result is a longer reserve. Caliber 3130 gives approximately 48 hours, so a watch left in a drawer over a weekend is likely to stop by Monday. Caliber 3230 raises that to approximately 70 hours, enough to carry it through a long weekend or a few days off the wrist. The 124060 is certified to Rolex's Superlative Chronometer standard of -2/+2 seconds per day after casing. Rolex introduced that standard in 2015, three years after the 114060 launched, and later extended it across its range, so later 114060s carry the same rating. 114060s made from 2012 to about 2015 were certified only to the COSC standard of -4/+6 seconds per day, which is tested on the uncased movement. On a later 114060 the difference is endurance and design generation, not rated accuracy.
Did the bracelet and clasp change?
Both watches wear an Oyster bracelet with the Glidelock extension, so the everyday experience is similar. Rolex describes Glidelock as a toothed mechanism with 10 notches of approximately 2 mm, which lets you adjust the length by about 20 mm without tools and wear the bracelet over a diving suit. Reports from the pre-owned market say the links and end pieces are not interchangeable between generations, so do not assume an older bracelet will fit the newer case. Confirm any bracelet swap with a watchmaker before buying parts.
Which one suits which buyer?
Choose the 124060 if you want the current design and the longer power reserve, and the 114060 if you prefer the compact 40 mm lineage and the broader lug look. Pre-owned buyers often weigh the 114060 as the last of the earlier generation, usually at a lower band than the newer watch, though that depends on condition, age and paperwork. Collectors who wear a watch daily tend to value the extra reserve, while those who like a slightly more traditional silhouette lean towards the older reference. Neither is a wrong choice, and both stay firmly in the classic no-date dive watch idea.
What should you check when buying either one?
- Reference and serial. Confirm the reference engraved on the case matches the paperwork and the movement generation you expect.
- Bracelet condition. Stretch and worn clasps are common on the older watch; check the Glidelock moves smoothly through its notches.
- Bezel and dial. Look for chips on the ceramic insert and consistent lume on the dial and hands.
- Service history. Ask for dates and receipts; see Rolex's watch care and service guidance for what servicing involves.
- What is included. Box, papers and extra links all affect the final band, so ask exactly what comes with the unit.

Quick answers
Is the Rolex 124060 the same as the 114060?
No. They look alike, but the 124060 is the newer generation with a 41 mm case, caliber 3230 and a roughly 70 hour reserve, while the 114060 is the 40 mm watch with caliber 3130 and a roughly 48 hour reserve.
Which has the longer power reserve, the 114060 or the 124060?
The 124060. Rolex gives approximately 70 hours for caliber 3230 against approximately 48 hours for caliber 3130.
Do the 114060 and 124060 have the same bezel?
Both use a black unidirectional Cerachrom bezel, so the main look and function are the same. Differences you will notice are in the case profile and lugs rather than the bezel.
Can I swap bracelets between a 114060 and a 124060?
Do not assume so. Reports suggest the links and end pieces differ between generations, so check with a watchmaker before buying any replacement parts.
