One of our favorite American-based dive watch specialists has released another water watch you’re sure to appreciate. Deep Blue’s Daynight Alpha Marine 500 Tritium T-100 Swiss Automatic may be a mouthful to pronounce, but you’ll like what you see at a glance.

The Deep Blue Daynight Alpha Marine 500 Tritium T-100 Swiss Automatic.

Deep Blue is known for its intense lume and superior water resistance, and this new model certainly fills the bill. The watch is cased in a 45mm 316L stainless steel case and is 15mm thick. Inside beats a Sellita SW-200-1 Automatic oscillating at 28,800 vph.

Visible through the 33mm dial aperture are the numerous flat and round self-illuminating tritium tubes, in this case complemented by a fully illuminated dial. Clearly its all about the glow on this watch. Even the 120-click ceramic bezel combines Superluminova numerals and markers with a tritium pip.

As expected, Deep Blues utilizes an extra thick sapphire crystal with AR coating underneath, and another crystal offers a view of the movement from the reverse side.

Water resistant to an impressive 500 meters, the watch head is held in place by a stainless steel bracelet with a multi-function safety and micro-adjustment deployant clasp. Price: $999.
