The catalogue holds eight chronograph families, from a 39 mm Sterling Chrono to a 46.5 mm Royal Chrono. Six of the eight describe the dial as “chronograph-style”, which reads like a design note about sub-dials that do not do anything.
It is not. Five of those six name a Seiko or TMI VK calibre in the same listing, two lines further down — and a VK is a working chronograph. The store is describing its own watches more cautiously than the spec sheet warrants, and that costs it buyers who read the word “style” and move on.
Quick Answer for Buyers
Seven of the eight name their movement: five run a VK63, one a VK64, one a VK67. All three are Seiko/TMI meca-quartz chronographs, so the sub-dials and the pushers work. The eighth, the Silver Compass, names no calibre and uses Hardlex rather than sapphire — it is the only one you cannot check from the listing. Four publish 100 M water resistance (Apex, Gold Summit, Lunarsteel, Saturn) and only the Saturn publishes a screw-down crown. Prices run from € 139.90 to € 205.90.
What “Chronograph-Style” Actually Means Here
A chronograph is a watch with a stopwatch built into it: press the top pusher and a hand starts timing, press it again to stop, press the bottom one to reset. The sub-dials count the elapsed minutes and hours. A watch with sub-dials that only display the running seconds or the date is not a chronograph, however much it looks like one, and the phrase “chronograph-style” is normally how a listing admits exactly that.
That is not the situation here. The VK series is Seiko’s meca-quartz line: a quartz movement for timekeeping with a mechanical chronograph module bolted on top. Timing is accurate to a quartz standard, the chronograph seconds hand sweeps instead of ticking, and it snaps back to zero on reset the way a mechanical one does. Seven of the eight listings name a VK calibre outright.
So on those seven the pushers work. The wording undersells the watch, and the two listings that describe the function plainly are the exceptions rather than the rule: the Lunarsteel is the only one that says “chronograph functionality”, and the Saturn is the only one that uses the word “stopwatch” — even though both run the same VK63 as three of the watches whose listings call it a style.
Movement, Glass and Water Resistance
| Family | From | Calibre named | Glass | Water resistance |
|---|---|---|---|---|
| Aero Chronograph | € 139.90 | VK64 | Sapphire | Not published |
| Royal Chrono | € 149.90 | VK67 | “Synthetic glass” | Not published |
| Silver Compass | € 159.90 | Not published | Hardlex | Not published |
| Sterling Chrono | € 185.90 | VK63 | Sapphire | Not published |
| Apex | € 199.90 | VK63 | Sapphire | 100 M |
| Gold Summit | € 199.90 | VK63 | Sapphire | 100 M |
| Lunarsteel | € 199.90 | VK63 | Sapphire | 100 M |
| Saturn | € 205.90 | VK63 | Sapphire | 100 M |
Read that table by price rather than by name and the ordering stops making sense, which is the most useful thing in it.
The Price Ladder and the Spec Ladder Disagree
The cheapest watch in the range is not the weakest. The Aero Chronograph opens at € 139.90 with sapphire glass and a named VK64. The Silver Compass costs € 20 more and gives you Hardlex, no calibre reference and no water rating.
Between them sits the Royal Chrono at € 149.90, which names a VK67 but describes its glass only as “synthetic glass” — the vaguest glass wording anywhere in the range, and a phrase that could cover several materials.
Then the four steel-bracelet models cluster at € 199.90 to € 205.90, and those four are the ones that publish 100 M. That is where the extra money goes: not into the movement, which is the same VK63 the € 185.90 Sterling uses, but into the case, the bracelet and the sealing.
Water Resistance Is Published on Four of the Eight
Apex, Gold Summit, Lunarsteel and Saturn all publish 100 M — two of them stated as 10 bar, which is the same figure. The other four publish nothing at all on the subject.
An absent rating is not a rating of zero; it means the listing does not make the claim. Treat it as unknown and keep those four away from water. Even on the four that do publish a figure, a chronograph has two extra holes in the case for the pushers, and pressing them underwater is what floods a watch that was otherwise rated for it.
Only the Saturn publishes a screw-down crown, and the crown is the largest opening in any watch case. It is also, at € 205.90, the most expensive of the eight — and it is the only listing in the range that calls the function a stopwatch. Those three facts sitting on the same product are unlikely to be a coincidence.
The Silver Compass Is the One You Cannot Check
Every other family in this group names a calibre. The Silver Compass does not, and it is also the only one with Hardlex rather than sapphire. Hardlex is hardened mineral glass — tougher than ordinary mineral, softer than sapphire, and it picks up marks from a door frame or a desk edge over a few years in a way sapphire does not.
None of that makes it a bad watch. At 44.5 mm across and 12 mm thick it is the flattest of the three large models, and its 23.8 mm strap is the widest in the range, which is part of why it wears as substantially as it does. But it asks you to take two things on trust that the other seven put in writing, and it costs more than the Aero, which puts both in writing.
Size: 39 mm to 46.5 mm
| Family | Case | Thickness | Band width | Worn on |
|---|---|---|---|---|
| Sterling Chrono | 39 mm | 13.5 mm | 20 mm | Steel bracelet |
| Apex | 40 mm | 12 mm | 20 mm | Steel bracelet |
| Gold Summit | 40 mm | 14 mm | 20 mm | Steel bracelet |
| Lunarsteel | 40 mm | Not published | 20 mm | Steel bracelet |
| Saturn | 40 mm | 14 mm | 20 mm | Steel bracelet |
| Aero Chronograph | 44 mm | 12.8 mm | 22 mm | PU leather strap |
| Silver Compass | 44.5 mm | 12 mm | 23.8 mm | Leather strap |
| Royal Chrono | 46.5 mm | 14 mm | 21.5 mm | Leather strap |
The split is clean. The five steel-bracelet models sit at 39 or 40 mm and the three leather models are all 44 mm or larger, so in practice you are choosing a size and a material together rather than separately.
The Sterling is the only one under 40 mm, and at 13.5 mm it is thicker than the 40 mm Apex — small on the wrist does not mean flat on the wrist. The Apex is the thinnest of all eight at 12 mm and the easiest to get under a cuff. The Saturn and the Gold Summit are 14 mm, which is what a screw-down crown and a 100 M case cost you in height.
At the top, the Royal Chrono at 46.5 mm is the largest watch the store sells. If your usual size is 40 mm, it will read as two sizes up, not one.
Which One, in One Line Each
Most watch for the least money: Aero Chronograph
Sapphire glass and a named VK64 at € 139.90, which is less than two of the watches that give you neither. The trade is the PU leather strap and no published water rating.
The one rated for real life: Saturn
100 M, a screw-down crown, sapphire, a VK63 and the only listing in the range that says stopwatch. It is the most expensive at € 205.90 and 14 mm thick, and both of those are the price of the sealing.
Under 40 mm: Sterling Chrono
The only one, at 39 mm. Sapphire and a VK63, on a steel bracelet, with no water rating published.
The thinnest: Apex
12 mm, 40 mm across, 100 M and a folding safety buckle. The closest thing here to a watch you can wear every day without thinking about it.
Gold rather than steel: Gold Summit
Same 40 mm case, same VK63, same 100 M, in a gold tone. The gold range comparison covers how it sits against the rest of the gold and rose gold models.
Questions Buyers Ask
Do the sub-dials actually work?
On the seven that name a VK calibre, yes — the VK series is a mechanical chronograph module on a quartz base, and the pushers start, stop and reset the timing hands. On the Silver Compass the listing names no calibre, so there is nothing published to answer the question with.
Is a meca-quartz chronograph worse than a mechanical one?
It is different rather than worse. You get quartz accuracy and a sweeping chronograph hand that resets instantly, without the servicing a mechanical chronograph needs. What you do not get is a mechanical movement to look at, and the battery has to be changed. Nothing in this range is a mechanical chronograph.
Can I swim with one?
Only four publish a water rating at all, and 100 M on a chronograph is not the same promise as 100 M on a diver, because of the pushers. Do not press them in water. If water resistance is what you are shopping for, the Saturn is the only one of the eight with both a published rating and a screw-down crown.
Which of them can I restrap?
The three leather models. The Aero takes 22 mm, which is a common size; the Royal takes 21.5 mm and the Silver Compass 23.8 mm, neither of which is a standard aftermarket width. The leather strap comparison lists the width of every leather model in the catalogue.
Where to Go Next
All nineteen chronographs, including the colour variations of each family, are in the chronograph collection. If a working stopwatch is not actually what brought you here and you wanted the mechanism on show instead, the open heart and skeleton comparison covers the two watches that do that. And if you are still deciding whether any of this is worth buying, the buyer’s guide takes the question from the top. If the movement is what you are choosing by, the quartz collection gathers every battery-powered model and the automatic collection the ones that wind themselves on the wrist.
