Officine Panerai has just unveiled two new special editions of their “Radiomir 3 Days Acciaio” that is set to debut at SIHH 2017. These two new timepieces are the first to faithfully mimic the fundamental characteristics of the original “Radiomir”.

This mythical watch in the Panerai catalogue all began with Type A ref# 3656, which was one of the earliest timepieces to be put on the market by this brand. Its launch occurred during war time, which complicates dating exactly when it happen. But, one can safely affirm it occurred between 1935 and 1938.

The 47mm case is made of stainless-steel, just like the original Radiomir and the comparisons don’t end there. Covering the dial is also a plexiglass crystal, while the transparent caseback applied was the typical sapphire crystal to be able to view the inner working parts. This may not be to everyone’s liking since plexiglass does scratch considerably easier than sapphire, but in honoring the original Panerai choose the former. So clearly this new Radiomir is aimed at vintage enthusiasts. But, in an attempt to minimize complaints Panerai has included an extra spare crystal in the package.

Its 12-sided bezel is made of brushed stainless-steel with polished angles and engraved with the words “OFFICINE PANERAI BREVETTATO”, which refers to the patented luminous substance used on the dials. Back in the 1930’s this was the way Panerai presented their watches to the authorities of the Royal Italian Navy. The case on this watch keeps water-resistance up to 30 meters (96 feet).

Time is exhibited on a simple dial available in either black or a “patina brown”. This “patina brown” is a totally new color being introduced to the Panerai lineup, which intends to mimic the discoloration that occurs over time on lacquered dials. If you weren’t aware and want to avoid this discoloration, you’d have to opt for an enamel dial, but many horology fans actually appreciate the extra character a watch gains with this material over time.

As we continue to analyze this watch there are more callbacks to its predecessor. There is a time-only indication without any seconds hand or sub-seconds. The hands pointing at the Arabic numerals 3, 6, 9, 12 and hour index markers have all undergone a luminescent coating, for an enhanced legibility. There is also an oversized onion crown, which was a mandatory necessity for military watches, in the era when soldiers had to wind the timepieces wearing gloves.
