Seiko Prospex Automatic SPB143J1 Special Edition Watch

The Watch

Seiko never stops innovating - and with the SPB143J1, the brand invites you to celebrate the 50th anniversary of its iconic Prospex line. Seiko's dive watches have reshaped the industry, opening up new possibilities for professional and passionate divers alike. This watch is sure to win you over with its refined style. It features a 40.5mm stainless steel case with a 13.2mm thickness, perfectly sized for a men's wrist. To protect the dial from shocks and scratches, a domed anti-reflective sapphire crystal sits on top. Above it, a black unidirectional bezel with Arabic numerals makes it easy to track your time underwater. At the 3 o'clock position, a screw-down crown in stainless steel allows for manual winding and hand-setting. The screw-down case back ensures water resistance to 20 atmospheres - dive with complete peace of mind.

The Dial

Chic and charming, this round dial features a sunray-brushed grey finish. Light-catching and luminous, it reveals its reflections with every movement of your wrist. At its center, three hands: two baton hands indicating hours and minutes, plus a slender seconds hand. Hour markers echo the same baton style. Both the hands and indexes feature LumiBrite treatment, keeping them luminous in the dark. A white minute track runs along the outer edge of the dial to assist with precision reading. The brand's signature appears beneath the 12 o'clock index, with the movement and water resistance noted above the 6 o'clock position.

The Movement

Powering this watch is an in-house automatic movement. Specifically, a caliber 6R35 with 24 jewels. It beats at 21,600 vibrations per hour. Its 70-hour power reserve offers impressive comfort. Accuracy is rated at -15/+25 seconds per day.

The Bracelet

This model sports a stunning stainless steel bracelet. Rugged enough for diving yet refined enough for everyday wear, it conforms perfectly to your wrist once sized. It fastens with a deployant clasp with push-button release.

Water Resistance

This model offers water resistance to 20 atmospheres, or 200 meters. A watch built to keep up with your deepest aquatic adventures - designed for freediving! Not afraid of water in the least, you can even use high-pressure cleaning equipment with this timepiece on your wrist. Showering, bathing, lap swimming, and freediving are all fair game. Just remember: never operate the crown or pushers while submerged, to protect the integrity of the movement.
