The Maker

THE CRAFT
BEHIND EACH
WATCH

"Every modification is done by hand — no assembly lines, no compromises. If it leaves my bench, it's right."

Hi, I'm Bek — a one-person shop based in Austin, Texas. What started as a hobby tinkering with my own Casio watches turned into something I couldn't stop doing. There's something deeply satisfying about taking a classic, reliable timepiece and making it yours in a way the factory never intended.

Every watch I mod starts as a genuine, authentic Casio. I don't cut corners on the base — the reliability you expect from Casio is still there. What I add is the color, the character, and the custom details that make it a piece you'll actually want to wear every day.

01
Genuine Base
Every build starts with an authentic Casio — never a knockoff. The movement, the battery life, the accuracy — all original Casio quality.
02
Color Filter
Precision-cut gel filters are applied to the watch face, transforming the display into any color while keeping full readability in all lighting.
03
Hydromod (Optional)
The case is filled with 100% pure silicone oil — boosting contrast, dramatically improving viewing angles, and raising water resistance to 100m+.
04
Strap & Adapters
Lug adapters bridge the 18mm lugs to 22mm options — rubber, NATO, nylon, or steel — for a premium fit. Original strap always included.
05
QC & Ship
Every watch is tested before it leaves. Packaged carefully, shipped from Austin TX with tracking. Free shipping on all orders.
