Produced for the first time in 1999, the Luminor Chrono model is a modern, highly technological watch, testament to the continuous developments Panerai carries out in materials, functions and design.The Panerai Luminor Chrono Daylight, made entirely from AISI 316L solid steel or brushed titanium, is a high precision chronograph fitted with a movement featuring chronograph functions on three counters: the Panerai OP XII calibre. It is available in some versions, with ivory, black or blue dial. The models with black and blue dials come with an alligator strap or with a brushed steel or brushed titanium bracelet.

The Luminor 1950 Chrono Rattrapante and Flyback watches represent an important evolutionary moment, since they introduce a newly conceived aesthetic with technical details of absolute value. The case reproduces a version from the 1950s, with rounded edges and a smoothly rounded bezel with polished finish, which confers a touch of classicism on an article with a markedly sporting tendency. The sapphire crystal too is unusual, with accentuated cambering of the edges, achieved by working the synthetic sapphire internally.

The Panerai Luminor 1950 Chrono Rattrapante is a split-seconds chronograph equipped with the Panerai OP XVIII calibre, an exclusive automatic movement distinguished by the system of operating the chronograph functions through twin column wheels.

The movement that equips the Panerai Luminor 1950 Chrono Flyback is the Panerai OP XIX. Apart from the typical indications of the standard chronograph, this calibre has a further function: permanent zeroing, otherwise known as flyback or retour en vol. If the zeroing push-piece is pressed while the chronograph is running, the large central hand is returned directly to zero, without having first to be stopped. By continuing to hold down the zeroing push-piece, the chronograph hand immediately begins a new measurement starting from zero.

With the back secured by screws, the Panerai Luminor Chronograph 40mm is water-resistant to a depth of 100 metres and the case is finished in two ways: the bezel is minor-polished while the caseband, the bridge of the lever device and the chronograph push-pieces, inserted obliquely in the caseband, are satin-finished, thus creating a sophisticated effect of contrast and depth between the different surfaces.
