Panerai Luminor Marina 8 Days Acciaio

While many brands tout their aviation heritage, Panerai, with its historical links with the Italian Navy, focuses on maritime (and sub-maritime) effectiveness. The brand prides itself on offering some of the very few timepieces that measure power reserve in days rather than hours and is releasing several new editions of its hardy Radiomir and Luminor models. The simplest and most handsome is the 44mm Luminor Marina 8 Days Acciaio, which will be available for one year. Featuring a completely in-house P.5000 manually wound movement with a power reserve of eight days, its everyday usability is largely a product of its Forties-inspired design, which keeps it simple with a stainless steel case, white dial with Arabic numerals, luminous dot markers, and a tan leather strap.
