The Panerai Luminor Quaranta (PAM01370) is a highly sought-after, contemporary luxury watch that brings the brand’s bold, historic dive-watch DNA into a versatile 40mm design. By scaling down the signature cushion-shaped case, Panerai makes its iconic aesthetic accessible for daily urban wear while retaining its legendary wrist presence.

• Case Construction: A 40mm AISI 316L satin/brushed stainless steel case features a high-polished fixed bezel. It includes the instantly recognizable Safety Lock crown protection bridge at 3 o'clock. 

• The Dial: A striking sun-brushed blue sandwich dial with luminous Arabic numerals and hour markers. It features a date window at 3 o'clock and a small seconds sub-dial at 9 o'clock. 

• Internal Movement: It is powered by the in-house automatic Panerai Calibre P.900. This self-winding engine beats at 28,800 vph, utilizes an Incabloc® anti-shock device, and delivers a robust 3-day (72-hour) power reserve. 

• Straps & Ecosystem: The watch features Panerai's Click Release System™ for quick toolless strap changes. It is standardly paired with a dark blue alligator leather strap but often includes a secondary strap like a blue rubber variant. 

• Water Resistance: Rated for 10 bar (~100 meters / 330 feet), making it fully capable of managing everyday exposure and swimming.
