When a collection grows, so does the question of where to put the watches. The Safewinder SmoothX 8 answers it with eight winder positions behind a lockable door and is aimed at collectors for whom four positions are no longer enough. Technically, it is the big brother of the SmoothX 4 and shares its controls, sleep mode and digital lock. In this data check, we mainly clarify two things: whether the extra cost over the four-watch model is worthwhile and how honestly the security claim of this box has to be classified.
Data check: Safewinder SmoothX 8 at a glance
The Safewinder SmoothX 8 belongs to the class of lockable winder boxes that combine winding and storage in one housing. Instead of four, it holds eight automatic watches, which it usually moves in two rows and keeps behind a digital lock. It clearly targets the larger collection, without changing the familiar operation of the smaller model. If you know the four-watch model, you will find your way around the eight-watch model immediately.
Under the surface, the same technology as in the SmoothX 4 is at work. Each of the eight positions can be programmed individually for speed and direction, controlled via a touch panel with LCD, complemented by LED interior lighting and the sleep mode. The following table summarises the verifiable key data according to manufacturer and retailer information as of July 2026.
Visually, the eight-watch model stays true to the line, with a carbon look and a mirrored front that showcases the watches behind glass. The gain over the four-watch model is therefore pure capacity, with no new design and no new function. That makes the purchase decision pleasantly straightforward.

Safewinder SmoothX 8 Carbon
- Eight individually programmable positions with the same touch control and LCD as the four-watch version
- Locked door with digital lock and emergency key, LED interior lighting and carbon look
- Significantly cheaper than any certified safe with eight winder modules
- Here too: lockable box instead of certified security protection; high collection values belong in the grade-tested safe
Security honestly put into context: not an EN 1143-1 safe
As tempting as eight locked positions seem, the key point remains the same as for the smaller model and weighs even more heavily for the eight-watch model: the Safewinder SmoothX 8 is not a security safe certified to EN 1143-1. The standard governs the tested burglary resistance of genuine safes and is the prerequisite for insurers to recognise high collection values at all. Without this certificate, even the box fitted with eight watches remains, in insurance terms, a lockable piece of furniture.
Precisely because more watch value often comes together in an eight-watch unit, an honest classification is particularly important here. The digital lock and locking mechanism reliably keep out dust, prying eyes and opportunistic access, but they do not replace tested burglary protection against prepared offenders. Anyone who bundles eight valuable automatic watches in one place also makes them a more attractive target, which is why an additional grade-tested safe from the watch safe buying guide deserves all the more serious consideration.
Our article on safe security grades explains the guideline values for the collection value at which each resistance grade makes sense. As a rule of thumb: the closer the total value of your eight watches gets to typical insurance limits, the more clearly the role of the SmoothX 8 shifts from value protection to a pure winding and organising device. It fulfils this role well, just not that of a safe.
The extra cost over the SmoothX 4: when it is worth it
The central purchase decision for the eight-watch model is not a technical one but an arithmetical one, because technology and operation are practically identical to the SmoothX 4. You do not pay the extra cost for better motors or more functions, but simply for double the capacity in one housing. That is a good deal precisely when you can foreseeably fill the additional positions, rather than keeping them turning empty for years.
The honest rule of thumb is therefore this: if you already want to keep five or more automatic watches in rotation at the same time, or know for certain that your collection will soon grow beyond four pieces, the eight-watch model works out cheaper than buying a second four-watch unit later. If you stay at three or four watches, however, you pay for empty space with the SmoothX 8 and are better served by the smaller model. A single case also saves floor space and needs only one power source, which counts against the two-box solution as soon as everything is meant to stand in one place.
Another often overlooked point is future-proofing. If you buy the eight-watch model, you have spare capacity for new additions and do not have to rethink your storage with every extra purchase. For active collectors, this peace of mind is a real, if hard to quantify, benefit.
Strengths and weaknesses in detail
The strength of the SmoothX 8 is its combined capacity without compromising on operation. Eight watches can be programmed individually, each with its own speed between 650 and 1,950 turns per day and its own direction of rotation; our TPD table provides the suitable values. In addition, there are the sleep mode, the LED interior lighting and the same lockable door as on the smaller model. For a collection kept in one place, this is the tidiest solution in the Safewinder range.
The weaknesses are the flip side of its size. Eight positions in two rows need noticeably more floor space and door clearance than the four-watch model, so you should check the dimensions against your intended spot before buying. Where the manufacturer does not state clear dimensions, it is worth checking the current retailer page rather than relying on estimates. And the most important reservation remains the lack of certification here too, which weighs even more heavily at the higher collection values of an eight-watch unit.
All in all, nothing changes in the quality of the movement with the eight-watch model, only in the quantity. That is a strength for everyone who is looking for exactly this quantity, and a weakness for everyone who will not make use of it. A half-empty eight-watch unit is ultimately an expensive four-watch unit, and this honesty belongs in every buying guide.
Who is the Safewinder SmoothX 8 suitable for
The SmoothX 8 is the right device for collectors whose collection has clearly exceeded the four-watch limit or will soon do so. If you regularly wear six, seven or eight automatic watches and want to keep them wound, you get all the positions here in one lockable case with unified control. It also makes sense as a forward-looking purchase if the collection is visibly growing and a second device would only be a matter of time anyway.
The eight-watch model is not the first choice for two groups. If you will permanently stay at a few watches, you pay unnecessarily for empty positions and are better served by the more compact SmoothX 4. And collectors with high insured values are better off separating a certified safe and a separate winder, as the category Safe with watch winder and the comparisons of multi-winders for six watches or more show. The box remains a convenience solution, not a security solution.
Editorial verdict
The Safewinder SmoothX 8 does exactly what the SmoothX 4 does, just for twice the number of watches, and that is how it should be judged. If you really need the eight positions, you get a coherent, tidy winding and privacy solution with individually programmable winders and a lockable door. If you do not need them, the four-watch model saves you real money without any technical sacrifice. Because the device convinces within the bounds of its honest claim and merely does not want to be a safe, our editorial team awards 4.0 out of 5 points.
