AE-1200 "NASA Royale" Custom Build

A space-inspired custom build with a white mission-themed face, blue and red details, and an orange band. Watch the small details come together, then see the finished watch on the wrist.

Independent custom build; not an official NASA product.
04 / Spotlight mod

Lume,
after dark.

In daylight, it keeps the clean digital look you know. When the lights go down, the display takes on a vivid blue glow. Add Lume to a custom build, alone or alongside other details.

Ask for LumeGlow brightness and duration depend on lighting and use. Photos show one Lume build.

F-94W Yellow Filter Build

A bold yellow display filter with matching face accents gives this build a fresh personality. Bring a favorite color or a reference image, and we can explore a filter treatment that fits your watch.

06 / Personalized gift builds

Give a watch with a story.

I made this watch for a friend with their wedding photo in the face and Florida and Louisiana flag details. It brings their story into something they can wear every day.

A photo, a shared place, or a meaningful date can become the detail that makes a gift personal.
