In this guide
Five dials, one case
Every Chronoking Racing uses the same 316L stainless steel case, polished and brushed, 38 mm wide, 13.4 mm thick and 46.5 mm lug to lug, under a double-domed sapphire crystal. Applied indexes with luminous material and an inner ring with luminous dots keep the time readable in low light. What changes is the dial.
The interchangeable bezel
The Chronoking Racing mixes vintage racing looks with a practical idea: the bezel comes off. You snap it on and off with your fingers, without tools, and a four-ball locking system holds the aluminium bezel in place. Swap the tachymeter bezel for another colour to move from a sporty look to a more refined one. The idea goes back to the 1960s, when Nivada Grenchen introduced interchangeable bezels on the Colorama VI women's collection.
Every model can be worn on leather, racing leather, rubber, the flat link bracelet or the beads of rice bracelet. See all interchangeable bezel watches.
The VK63 meca-quartz movement
Inside is the TMI VK63, a meca-quartz chronograph. Quartz keeps the time, so there is nothing to wind, and a mechanical module runs the chronograph: the central hand sweeps smoothly and snaps back to zero when you reset it. The Chronoking runs on an SR936SW silver oxide battery that lasts about three years, with accuracy rated at ±20 seconds per month.

How to use the tachymeter
The tachymeter scale on the bezel turns the chronograph into a speed calculator over a known distance:
- Start the chronograph as you pass a marker.
- Stop it after one kilometre or one mile.
- Read the average speed where the chronograph seconds hand stops: one kilometre in 30 seconds stops it at 120, an average of 120 km/h.
