The Panerai Luminor Quaranta is the 40 mm expression of the Luminor design: a cushion-shaped case and the collection’s signature crown-protecting lever in a smaller size. Its BiTempo models add a second time-zone function. Panerai’s 2024 catalogue lists several BiTempo references, while its US product page for PAM01641 gives a detailed example in Goldtech.

What is the Panerai Luminor Quaranta?

Quaranta means “forty” in Italian. Panerai describes the collection as carrying Luminor design into a 40 mm case. The brand identifies the cushion-shaped case and crown-protecting lever as defining Luminor features, and notes a discreet minuterie inspired by watches from the early 2000s. Panerai’s PAM01641 product page describes the Quaranta as capturing Luminor’s aesthetic in a smaller 40 mm case.

What does BiTempo mean?

BiTempo is the dual-time, or GMT, branch of the Quaranta collection. Panerai says it allows the wearer to read local time and a second time zone. On the PAM01641 page, the listed functions are hours, minutes, small seconds, date and GMT12H. Check the exact reference for how the second time zone is displayed; the catalogue’s general description does not establish every dial detail across the range.

Which Luminor Quaranta BiTempo models are listed?

Panerai’s 2024 catalogue is a dated snapshot of four BiTempo references. It lists PAM01640 and PAM01641 in brushed steel, and PAM01365 and PAM01367 in Panerai Goldtech. For PAM01641, the catalogue’s steel listing differs from the currently accessible US product page, which identifies that reference as Goldtech. Confirm the material against the specific model page and market rather than assuming the catalogue entry or a reference number alone settles it. The catalogue does not establish that every listed watch remains available in every market in 2026.

PAM01641: specifications on Panerai’s US page

The US product page identifies PAM01641 as a 40 mm Goldtech BiTempo with a black dial and see-through sapphire caseback. Panerai lists its movement as the automatic P.900/GMT calibre, with 23 jewels, a frequency of 28,800 alternations per hour, one barrel and a three-day power reserve. Its listed functions are date, GMT12H, small seconds, minutes and hours.

  • Water resistance: 10 bar, approximately 100 m, according to the product page.
  • Strap: 22/20 mm, with Panerai’s PAM Click Release System. The page also lists an additional black rubber strap.
  • Strap changes: Panerai says its click-release system permits changes without a tool.

Those details apply to the cited US PAM01641 page. Check the product page for your region and exact reference before relying on them for another Quaranta.

  • Black genuine rubber strap paired with a black/blue dial, combining durability, comfort, and style for active men’s lifestyles.
  • Case material: the 2024 catalogue lists steel and Goldtech variants, but PAM01641’s material differs between that catalogue and the current US page.
  • Time display: BiTempo denotes local time plus a second time zone; check the reference’s page for its specific GMT implementation.
  • Dial layout: compare dial color, luminous Arabic numerals and markers, date position and small-seconds display where details are published.
  • Strap fit and interface: use the exact reference’s stated width and attachment system. A nominal 22/20 mm size by itself does not establish compatibility with a third-party strap.
  • Availability and terms: confirm local stock, price and warranty conditions with Panerai; a catalogue entry is not proof of current availability.

Strap fit and warranty for PAM01641

For PAM01641, Panerai specifies a 22/20 mm strap with its PAM Click Release System and lists an additional black rubber strap. If choosing another strap, verify both the precise reference and its attachment; matching the stated width alone may not be enough.

The cited US product page says eligible watches bought within the preceding two years may qualify for an extended International Limited Warranty of up to six years through Pam.Guard. Eligibility depends on purchase, registration and regional terms, so check the current conditions with Panerai rather than treating the extension as automatic.

Water resistance and availability

The 2024 catalogue lists 10 bar (approximately 100 m) water resistance for its four BiTempo references, and the PAM01641 US page also lists 10 bar. That rating is a published specification, not a substitute for checking the instructions for a particular watch or its service condition. Panerai’s reviewed materials do not establish a complete current worldwide lineup, regional inventory, current pricing, a collection launch date or a full history of the range. Verify the exact watch and local terms directly with Panerai.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
