If you’re familiar with the history of Panerai, then you will know that Officine Panerai used to supply the Italian Royal Navy in their operations during World War II.
With a case made of red gold or stainless steel that closely follows the design of the first Radiomirs made for the Italian Royal Navy and the sophisticated finish of the P.50000 manufacture movement.
The calibre P.5000 features a variable inertia balance. This enables a watchmaker to adjust the watch by turning the small timing screws on the outside of the balance wheel. This kind of balance and method of adjusting is considered much better than a balance without inertia screws, because the balance spring is free, without so-called curb pins.
The curb pins are used to modify the active length of the balance spring (or hair spring) and this creates a bend in the fragile spring that cannot be changed.
The watch is powered by the P.5000 hand-wound mechanical calibre a hand-wound mechanical movement with 21 jewels, Glucydur balance, 21.600 alternations/hour, and anti-shock. The movement is visible through the sapphire crystal window set in the back. It has been completely developed in the Officine Panerai manufacture at Neuchâtel. A large plate with brushed finish and diamond-polished chamfering almost completely conceals the mechanism, while revealing the variable inertia balance. The long running power reserve of eight days is achieved with two spring barrels connected in a series.
The case is 44mm in diameter and is immediately recognisable by the bridge device with locking lever to protect the winding crown.
The Luminor Marina 8 Days Oro Rosso is part of Panerai’s Historic Collection. It comes on a strap of black leather in the case of the steel version, and brown alligator in the red gold version, with a buckle made of the same material as the case.
