The Peacock SL3001 and PT5000 are both high-beat automatic watch movements used in current enthusiast watches. On paper they share several important features: both run at 28,800 vibrations per hour (4Hz), support automatic and manual winding, stop the seconds hand for precise setting, and include a date mechanism.
That does not make them interchangeable, and it does not mean that one is automatically more accurate, reliable or premium. Movement performance depends on the specific grade, regulation, assembly, lubrication, handling and the complete watch around it.
This guide compares the documented movement specifications first, then shows how the current Watchdives WD007 V4 uses PT5000 and SL3001 configurations in the same titanium dive-watch platform.
SL3001 vs PT5000 at a Glance
| Specification | Peacock SL3001 | PT5000 |
|---|---|---|
| Movement type | Automatic mechanical | Automatic mechanical |
| Frequency | 28,800 vph / 4Hz | 28,800 vph / 4Hz |
| Jewels | 28 | 25 |
| Power reserve | At least approximately 41 hours | Approximately 38 hours |
| Manual winding | Yes | Yes |
| Hacking seconds | Yes | Yes |
| Date mechanism | Yes | Yes |
| Diameter | Approx. 26.0mm | Comparable compact automatic architecture; check the movement supplier specification for the exact production version |
| Thickness | Approx. 4.8mm | Check the movement supplier specification for the exact production version |
The headline differences are therefore modest: the SL3001 has a higher jewel count and a somewhat longer stated reserve, while both movements operate at the same 4Hz frequency and provide the core functions many buyers expect from a modern automatic calibre.
What Does 28,800 vph / 4Hz Mean?
A movement running at 28,800 vibrations per hour completes eight semi-oscillations per second, commonly described as a 4Hz beat rate. This creates a smoother-looking seconds-hand motion than lower-frequency mechanical movements and gives the regulating system more oscillations over a given period.
Beat rate by itself does not prove that a movement is more accurate. Actual timekeeping depends on regulation, positional behavior, shock, temperature, lubrication and the specific example of the movement.
Peacock SL3001: Key Characteristics
The SL3001 is a compact high-beat automatic movement produced by Peacock. Its current documented specifications include a 28,800 vph frequency, 28 jewels, automatic and manual winding, hacking seconds and a date mechanism.
Its stated power reserve is at least approximately 41 hours. That gives it a modest reserve advantage over the approximately 38-hour figure commonly specified for the PT5000, but the practical difference is only a few hours and should not be treated as a universal quality ranking.
The SL3001 is approximately 26.0mm in diameter and 4.8mm thick, which allows it to work in relatively slim automatic watch cases.
PT5000: Key Characteristics
The PT5000 is another 4Hz automatic movement used widely in enthusiast-focused watches. It runs at 28,800 vph, uses 25 jewels, supports automatic and manual winding, includes hacking seconds and provides a date mechanism.
Its commonly stated power reserve is approximately 38 hours. As with any mechanical calibre, real-world reserve can vary with mainspring condition, winding state and use.
The PT5000 has become familiar in compact automatic watches because it combines a high beat rate with a relatively slim architecture. The movement name alone, however, does not establish how well a finished watch has been regulated or assembled.
Does the SL3001's 28-Jewel Count Make It Better Than the 25-Jewel PT5000?
No. Jewel count should not be used as a simple quality score.
Jewels are low-friction bearing surfaces placed where the movement design requires them. A movement with more jewels is not automatically more accurate, more durable or more expensive. The useful question is whether the movement has the appropriate bearings for its architecture and whether the complete calibre is manufactured, assembled and maintained correctly.
For this comparison, the difference between 28 and 25 jewels is a factual specification—not a reason by itself to rank one movement above the other.
Is the SL3001's Power Reserve Meaningfully Longer?
The documented figures put the SL3001 at at least approximately 41 hours and the PT5000 at approximately 38 hours.
A three-hour difference can matter if you frequently leave a watch unworn overnight or rotate several watches, but it is not a dramatic difference. Both remain roughly in the range where a watch may stop after being left unworn for a day and a half to two days, depending on how fully it was wound.
If extended off-wrist reserve is a major priority, neither figure should be confused with the 60-, 70- or 80-hour class found in some other modern movements.
Do Both Movements Support Hand-Winding and Hacking?
Yes. Both movements support manual winding and hacking seconds.
Manual winding lets you add energy through the crown when the watch has stopped or has not received enough wrist motion. Hacking stops the seconds hand when the crown is pulled to the time-setting position, which helps synchronize the watch more precisely.
Follow the instructions for the specific watch when winding or setting it. A movement family may appear in watches with different crown designs and user instructions.
How Watchdives WD007 V4 Uses SL3001 and PT5000
The current Watchdives WD007 V4 provides a useful real-world comparison because PT5000 and Peacock SL3001 variants share the same basic watch platform.
The WD007 V4 uses a Grade 2 titanium case with a 42mm size, 48.95mm lug-to-lug measurement and 12.2mm thickness including its double-domed sapphire crystal. It is rated to 200m water resistance and includes a screw-down crown, 120-click unidirectional bezel and functional helium escape valve.
Band options vary by configuration and include nylon, mesh, Grade 2 titanium bracelet and FKM rubber. The movement is determined by the selected variant rather than by the WD007 V4 model name alone.
Current PT5000 Configuration
At the latest Shopify check, the PT5000 was tied to the White-Blue Bezel configuration. Nylon and mesh versions were purchasable at the time of the check, while the titanium-bracelet and FKM configurations were unavailable.
This is important because choosing PT5000 is not only a movement decision. It also limits you to the dial/bezel and band configurations currently paired with that movement.
Current SL3001 Configurations
The current SL3001 range is broader. It includes C3 Black Calendar, C3 Black No Calendar, White-Black, Blue, BGW9 Black and Green configurations, with availability varying by band.
The green version uses a bronze-tone electroplated titanium bezel. It should not be described as a solid-bronze bezel.
If you prefer a wider range of dial, lume and band choices, the current product structure gives the SL3001 more configuration options. That is a product-availability advantage, not proof that the movement itself is superior.
Does Movement Choice Change the WD007 V4's Water Resistance?
No movement specification by itself establishes water resistance. The WD007 V4's stated 200m rating comes from the complete watch construction, including the titanium case, crystal, crown, case back, seals and assembly.
Do not infer that one movement version is better for diving simply because the calibre differs. Check the complete product specification and the selected variant.
What About Accuracy?
A simple SL3001-versus-PT5000 accuracy winner would be misleading without comparing the exact movement grade, regulation target and actual tested watches.
Both are 4Hz mechanical movements. Individual examples can perform differently depending on factory regulation, position, power state and wear. If accuracy is your priority, use the specification or measured performance of the exact watch rather than relying on the movement name alone.
Which Movement Should You Choose in the WD007 V4?
Start with the complete variant rather than trying to choose a movement in isolation.
- Choose a PT5000 WD007 V4 configuration if you specifically want the currently offered White-Blue Bezel version and its available band choice.
- Choose an SL3001 WD007 V4 configuration if you prefer one of the broader current dial, lume, date/no-date or bezel options paired with SL3001.
- Do not choose solely by jewel count. 28 versus 25 jewels is not a universal quality ranking.
- Do not choose solely by the few extra hours of reserve. The difference is useful to know but relatively small.
- Check live inventory. Movement, color and band combinations can sell out independently.
