The Q-Matic Rotoris Astonia: where racing heritage meets everyday precision
Chronographs have always occupied an interesting space in watchmaking. On one side, there are mechanical versions with their springs, gears, and the kind of craftsmanship that demands significant ongoing care; on the other, standard quartz chronographs that keep perfect time but often feel lifeless when the pushers get pressed.
The Rotoris Astonia exists as a third option that makes more sense for how most people actually live. It’s a racing-inspired chronograph built around hybrid Q-Matic movement technology that takes the best parts of both approaches and leaves the rest behind. Each watch carries its own identity and a spot in a public ownership registry.
Q-Matic Technology Explained
The TMI VK63 calibre inside the Astonia operates on a fairly straightforward principle. Different parts of the watch need different things, so different technologies handle different jobs.
Timekeeping runs on quartz. The oscillator vibrates at 32,768 Hz, which is standard for quartz movements. This keeps the watch accurate to within a few seconds each month. No winding needed. No regulation drift over time. The battery lasts somewhere between three and five years, depending on how much the chronograph gets used. Most owners will end up closer to five years unless the timing function sees heavy daily use.
The chronograph complication is where things get mechanical. Real physical parts move when the pushers get pressed. Gears engage. Springs compress. Levers shift position. The top pusher starts the timing function with actual mechanical resistance that travels through the pusher stem. The chronograph hand begins moving at five increments per second instead of the single tick most quartz chronographs do. The difference is noticeable. The hand sweeps with fluid motion rather than stuttering around the dial.
When timing stops and the bottom pusher is pressed, the reset mechanism activates. The hand doesn’t crawl back to zero. It snaps there instantly, every single time.
What the Case Brings
The case measures 42mm across. 316L stainless steel forms the case construction. This particular grade gets chosen for watch cases because it resists corrosion well and holds up to regular contact with skin, sweat, and the environment.
The dial is sapphire crystal. This material is significantly harder than mineral glass or acrylic. Regular daily activities won’t scratch it. Keys, desk edges, doorframes: the thousand small contacts a watch makes during normal wear won’t leave marks.
The VK63’s architecture stays relatively flat, which translates to a case that sits comfortably on the wrist without sticking up awkwardly.
5 ATM water resistance handles daily situations perfectly.
The bracelet is stainless steel too, matched to the case finish and sized to maintain proportion with the 42mm diameter.
Reading the Dial
Three sub-dials sit on the main dial face in what’s called a tri-compax arrangement. This layout comes straight from racing chronographs of the 1960s and 70s.
One sub-dial counts chronograph minutes up to 60. Useful when timing anything longer than a minute. Another sub-dial displays running seconds for the main time function. The third shows 24-hour time.
The Tachymeter Function
The bezel carries a tachymeter scale engraved into it. This isn’t decorative. It’s a calculation tool that’s been part of racing chronographs for decades and still has genuine applications.
The tachymeter calculates average speed over a known distance. Start the chronograph when something crosses a starting point. Stop it when that same thing crosses a point exactly one kilometre or one mile away. The chronograph hand now points directly at a number on the tachymeter scale. That number is the average speed in kilometres or miles per hour.
Limited Numbers, Public Registry
Every watch gets a unique serial number engraved on it. That number and the owner’s name go into a global registry that anyone can access online.
These aren’t mass-produced watches. Check any serial number against the registry. If it matches and shows the current seller as the registered owner, it’s legitimate.
The registry currently includes many known faces like F2 racing driver Kush Maini, tennis player Sumit Nagal, and actor Vivek Oberoi among its listed owners. Every entry is public. Anyone can see who owns which numbered piece.
The Astonia has also found its way into the collections of prominent names such as Tanmay Bhat, whose association with the timepiece offers another perspective on the watch and its growing community of owners.
Who This Watch Suits
The Astonia makes sense for almost all types of buyers. People who actually use chronographs for timing rather than just wearing them for aesthetics. Track day enthusiasts timing laps. Athletes tracking intervals. People who cook multiple dishes and need precise timing. Anyone who regularly measures elapsed time for work or hobbies.
Fully mechanical chronographs offer romance and traditional craftsmanship. They’re beautiful pieces of engineering. But they’re also expensive, require periodic servicing, need regular wear or winding, and can be temperamental. That’s fine for collectors and enthusiasts who want that experience. For those exploring the wider world of automatic watches, the mechanical construction and maintenance involved are often part of the appeal.
Standard quartz chronographs are reliable and affordable. But most use electronic motors to drive the chronograph functions. The pushers feel mushy. The hands jump in single-second increments. There’s no tactile satisfaction in using them.
The Astonia sits between these two extremes. Quartz timekeeping means it’s accurate and requires minimal maintenance. Mechanical chronograph components mean it feels engaging to use. The price reflects this middle position. Lower than mechanical constructions because manufacturing is simpler. Higher than basic quartz because genuine mechanical parts actually do work.
As a Q-Matic watch, the Astonia takes a different approach to the relationship between quartz accuracy and mechanical interaction. The result is a chronograph designed around how the wearer actually uses it, rather than fitting neatly into either traditional category.

Final Thoughts
The Rotoris Astonia, with its Q-Matic movement, provides quartz accuracy without the blandness of typical quartz chronographs. The tachymeter has a nice texture.
For people who time things regularly and want something dependable with character, this approach makes logical sense. Hybrid technology solves real problems. Quartz eliminates winding and regulation concerns. Chronograph components preserve the engaging aspects of operation.
