VK63 Meca-Quartz
Quartz accuracy for timekeeping. Mechanical chronograph for the snap-back reset. Press stop, press reset — the hand snaps to zero instantly. The most satisfying chronograph reset at any price.
Full Yellow Silicon
Yellow silicon strap that matches the dial for a cohesive, bold look from wrist to case. Sweat-resistant, water-resistant, dries immediately. Built for active daily wear.
Yellow Chronograph Dial
A vivid yellow dial with contrasting black chronograph subdials and gold-tone case details. Impossible to miss in any room — the watch nobody else is wearing.
Genuine Sapphire
Rated Mohs 9 — the same hardness as a ruby. Keys, desk surfaces, belt buckles, gym equipment — none of it scratches sapphire. After a year of daily wear, the crystal looks identical to day one.
40mm Stainless Steel
A balanced 40mm stainless steel case with 47.5mm lug-to-lug and 20mm lug width. Large enough to read easily, small enough to slip under a shirt cuff. 50m water resistance for rain and hand washing.

Yellow Dial.
Yellow Strap.
Nothing Else Like It.
Yellow is the colour that gets noticed. On the wrist at the gym, at a car event, on the morning commute — the ZJani Mods Yellow Silicon is the watch nobody else in the room is wearing.
The yellow silicon strap matches the dial for a cohesive, confident aesthetic from wrist to case. No generic black rubber here — full yellow, head to tail.
Gold-tone case details and a black bezel complete the look: sporty, bold, and built for a man who doesn’t want to blend in.

Frequently Asked Questions.
Is this watch automatic or quartz?
It’s a VK63 meca-quartz movement — a hybrid. The timekeeping is quartz (accurate to within seconds per month, no drift), and the chronograph is mechanical (the snap-back reset returns the hand to zero in a single decisive press). Battery lasts about 3 years and any watchmaker can swap it.
Is the yellow strap comfortable?
Yes — the yellow silicon strap is soft, flexible, sweat-resistant and water-resistant. It dries immediately after any water exposure and doesn’t degrade in heat or humidity. Perfect for active daily wear through gym, run or weekend.
Can I wear it in the shower or swim?
50m water resistance is enough for rain, hand-washing and splashes. Not designed for swimming, diving or hot showers — steam and chlorine can shorten the life of the seals.
How big does 40mm wear?
40mm with a 47.5mm lug-to-lug is balanced on most wrists — large enough to read easily, small enough to slip under a shirt cuff. Comfortable for daily wear even at a desk.
Does it come with a warranty?
Yes — 180-day international warranty, 30-day returns and free worldwide insured shipping. Every watch arrives in protective packaging with a warranty card. Email Kevin at support@zjani-mods.com if anything isn’t right.
