The Peacock SL3001 is a slim, high-beat automatic movement used in a growing number of enthusiast watches. This guide focuses on the movement itself: its documented specifications, what 4Hz means in practice, why its slim architecture matters, and current Watchdives examples that use it.
The core specifications below are based on Peacock's current official SL3001 specification page. Where a finished watch uses the movement differently, the watch-level specification should take priority.

What Is the Peacock SL3001?
The SL3001 is part of Peacock's slim automatic movement range. Its combination of a 4.80mm movement thickness and 28,800 vph frequency makes it useful for watch designs that want a relatively slim mechanical architecture without dropping to a lower beat rate.
Peacock lists 28 jewels, automatic and manual winding, stop seconds and a running time of at least 41 hours. These are movement-level specifications. They do not guarantee the accuracy, regulation, case thickness or water resistance of every finished watch that uses the calibre.
What Does 28,800 vph / 4Hz Mean?
At 28,800 vibrations per hour, the regulating system runs at 4Hz. In practical terms, the seconds hand advances in smaller visible steps than on many lower-frequency mechanical movements, which usually creates a smoother-looking sweep.
A higher beat rate does not automatically make a watch more accurate. Real-world timekeeping depends on regulation, positional behavior, assembly, lubrication, shock, temperature and the individual movement.
Why Does the 4.80mm Thickness Matter?
Movement thickness is only one part of total watch thickness, but a slimmer calibre gives designers more room to control case height. Crystal shape, dial construction, hand stack, case back and water-resistance architecture still affect the final dimensions.
A current example is the Watchdives WD50FS SL3001 Automatic Watch V3. It uses the SL3001 in a 40mm vintage-style dive watch and lists a 12.2mm overall thickness including its top-hat crystal.
How Long Is the SL3001 Power Reserve?
Peacock specifies a running time of at least 41 hours. That means a fully wound movement is designed to continue running for roughly a day and a half or longer under the stated movement specification.
Actual running time in a finished watch can vary with winding state, movement condition and use. A published reserve should be treated as a specification target rather than a guarantee that every watch will stop at the same exact hour.
Does the SL3001 Hand-Wind and Hack?
Yes. Peacock lists both manual winding and stop seconds.
Manual winding lets you add power through the crown when the watch has stopped or has not received enough wrist motion. Stop seconds, often called hacking, stops the seconds hand during time setting so the watch can be synchronized more precisely.
Does the SL3001 Have a Date Function?
Peacock's official specification lists a date display and corrector as part of the movement architecture. A finished watch may expose that date function, hide it behind a no-date dial, or use a configuration chosen by the watch manufacturer.
For that reason, do not assume that every SL3001 watch has the same crown positions or date-setting behavior. Check the instructions and product specification for the exact watch.
Which Current Watchdives Watches Use the SL3001?
Current Watchdives listings show the SL3001 in more than one product family.
- Watchdives WD50FS / WD50FK V3 — a 40mm vintage-inspired automatic dive watch built around the SL3001 high-beat movement.
- Watchdives WD007 V4 — selected configurations use the Peacock SL3001, while other configurations use PT5000. Check the selected variant before ordering.
- Watchdives WD007 Top Hat Sapphire — the current listing also identifies PT5000 / Peacock SL3001 movement options depending on configuration.
Availability and movement pairing can change by variant, so the live product page is the authoritative source for the exact configuration being purchased.
SL3001 vs PT5000: Are They the Same?
No. They are separate movement families, although both are commonly seen as compact 4Hz automatic options.
The SL3001 is officially specified at 28 jewels and at least 41 hours of running time. The PT5000 has different published specifications and appears in many of the same enthusiast-watch categories. The useful comparison is not simply “which name is better,” but how each movement is implemented in the exact watch.
For the side-by-side comparison, read our dedicated SL3001 vs PT5000 guide. Keeping the comparison on its own page avoids mixing comparison intent with this movement-reference guide.
Is the SL3001 a Good Movement?
The documented specification is competitive for its category: 4Hz frequency, 28 jewels, manual winding, hacking seconds, a slim 4.80mm architecture and at least 41 hours of running time.
Those numbers alone are not enough to rank reliability or accuracy. Finished-watch performance also depends on regulation, quality control, assembly and servicing. When evaluating a watch, use the movement specification together with the case, warranty, water resistance, manufacturer support and the exact product configuration.

SL3001: The Practical Takeaway
The SL3001's main documented strengths are straightforward: a slim 4.80mm architecture, 4Hz frequency, 28 jewels, hand-winding, hacking seconds and at least 41 hours of running time. That combination helps explain why it appears in current slim or enthusiast-focused automatic watches.
