Perseo Sub 90531 — 200m Automatic Diver with Seiko Movement

Perseo Sub 90531 — The Diving Icon of Italian Tradition

An authentic Italian diver's watch that combines the historical watchmaking tradition of Perseo — official supplier to the Italian State Railways since 1927 — with the modern demands of diving and water sports enthusiasts.

The Brand: Perseo

Perseo is a historic brand in Italian watchmaking, founded in Bologna and famous for supplying watches to the Italian State Railways for almost a century. Today, Perseo continues to produce Swiss-quality timepieces with Italian design, combining railway reliability and contemporary style.

Design and Dial

The black dial with blue nuances gives this Sub a sporty yet elegant character. The unidirectional rotating bezel features luminescent markers for perfect legibility even during night dives. The applied indices and hands are treated with luminescent material to ensure visibility in all lighting conditions.

Case and Construction

The 41mm 316L stainless steel case — the same steel used in surgical applications — ensures corrosion resistance and long-lasting durability. The screw-down crown guarantees water resistance up to 20 ATM (200 meters), allowing for safe professional diving.

Movement

At the heart of this Perseo Sub beats the Seiko NH35 caliber, an automatic Japanese movement renowned for its reliability and precision. With a power reserve of approximately 41 hours, this caliber ensures excellent performance for daily and sports use.

Crystal

The scratch-resistant sapphire crystal protects the dial from impacts and abrasions, maintaining perfect legibility over time. The anti-reflective coating ensures clear vision in all lighting conditions.
