About this watch
Design
The Diamond Astro Skeleton Mason Gold opens the Astro's 42.5mm tonneau case set with lab-grown diamonds to reveal its beating heart — an open skeleton dial that lays the mechanics bare, framed in frosted stainless steel and capped with an exhibition case back.
Movement
Inside runs a Japanese Seiko NH70 automatic that winds through the motion of your wrist — no battery, just engineering you can watch in motion.
Wear & water resistance
Rated to 50m (5 ATM), it shrugs off rain and hand-washing. A premium rubber strap makes the sculptural case sit light and secure all day.
Who it's for
For the mechanical-watch curious who want movement and modern architecture on one wrist.
New, boxed and warrantied — free US shipping.

Customer reviews
The Diamond Astro in Mason Gold is ridiculous in the best way possible. VVS lab diamonds on the bezel and a skeleton dial. Absolute head turner.
The shape combined with the gold and diamonds makes it look like a 6-figure watch. The automatic movement looks incredible ticking away.
You don't wear this to blend in. It's extremely flashy. 4 stars because it's definitely a special occasion watch, not a daily driver.
She bought it for my 30th birthday. It's the craziest piece in my collection. The setting on the diamonds is incredibly clean.
Paul Rich didn't cut any corners here. The weight, the finish, the VVS stones-everything feels incredibly high-end.
