The D4 Meridian 39mm is back in stock in both Black and Navy.

Designed to be our ideal everyday dive watch, the D4 combines solar power, full USA assembly, and 20ATM water resistance in a compact, comfortable 39mm case.

The Black version features a polished ceramic bezel for a sharper, more refined look, while the Navy retains its reserved matte ceramic finish.

Built from durable 316L stainless steel and fitted with a single-domed sapphire crystal with AR coating, the D4 is designed to handle daily wear without feeling oversized.

Whether you’re on a surf session, timing something on the grill, or just spending long days outside, the D4 Meridian was made to be the kind of watch you never have to think twice about wearing.

39mm vs. 42mm Dive Watches

"It's important to keep in mind sizing while considering which D4 model is right for you. When making a decision on the size, it ultimately comes down to wrist size and personal preference. For those with wrists over 7.25 inches, we generally recommend the 42mm case for a balanced and proportional fit. If you have smaller wrists or simply prefer a more compact and classic look, the 39mm size is an excellent choice.

On my 7.75” wrist, I personally prefer the smaller size, as it has a retro look and fits well under a wetsuit.

Both sizes are designed with timeless proportions and ergonomic comfort, so whichever you choose, you’ll get a watch that feels great on the wrist and looks incredible in any setting."
