Let’s talk about caliber P.5000 for a minute. It is a significant motor: two mainspring barrels which you can readily see running in both large stones, providing eight days of running time in 3hz/21,600 vph. The mainspring barrels operate in series, pushing torque via a really classically arranged going train, with the centre wheel visible through a large cutout in the plate. I guess technically speaking we would have to call this a 3/4 plate motion as the next wheel bridge is not really a bridge at the typical sense of this word, but instead the result of creating the cutout. That cutout plus the form of the major plate round the equilibrium give a very aesthetically pleasing, but still pragmatic impact, which is totally suitable for what was, after all, initially meant to be a tool watch, plain and simple. The moving train is organized so the fourth wheel is exactly opposite the crown, which is precisely where you would find it in a pocket watch, and if you would like a tiny seconds dial where it would happen to be in one of the Angelus pocket opinion powered Panerais all you need to do is conduct the wheel pivot through the dial and put a hand on it (which was exactly what Panerai did together with the PAM 510).The balance, which is held in place by a very solid looking bridge, seems somewhat small for the motion but then again, that is probably just because the movement’s so large; at 15 3/4 lignes, or simply about 35.7 mm, it is a pocket — watch rather than a wristwatch caliber (unless you’re at the bigger-than-average-wristwatch business, that Panerai manifestly is). In general, we think it’s an impressive piece of work — we’ve used the term sturdy and sturdiness is really much the takeaway belief one has of the P.5000. Interestingly, incidentally, the P.5000 includes a free-sprung, flexible mass equilibrium, which is a really wonderful touch, particularly at this price point — if you look carefully at what seems like the regulator you’ll see that it is actually not a regulator, but a stud carrier (in other words, the carrier to the stud to which the outer terminal of the balance spring is attached). The screws holding the equilibrium bridge in place run through threaded kayaks onto the bridge and can be employed to correct end-shake (the quantity of vertical “play” between the tips of the equilibrium staff as well as the endstones of the shock-jewel assembly.
Panerai‘s history in watchmaking essentially boils down to two models: the wire-lug Radiomir of the thirties and the later Luminor with its signature crown locking mechanism that came in the subsequent decade. But in between the two was a transitional model, essentially a Luminor without the crown locking device. That timepiece is the basis for the whole Radiomir 1940 collection, including the brand new Radiomir 1940 Marina Militare 3 Days Acciaio PAM00587.
Modelled on the Radiomir reference 6152/1, the Radiomir 1940 Marina Militare is feels just like a Luminor 1950 PAM372 with the crown lock mechanism removed. It looks and feels historically correct, right down to the “double pencil” gilt hands.
“Marina Militare” is a phrase that excites many a Panerai Watches For Ladies Replica enthusiast as several times in the past Panerai stated, without exceptions, that the phrase would no longer be used on its timepieces as it belonged to the Italian Navy. But “Marina Militare” inexplicably makes its way to the dial here.
As with most of Panerai’s vintage-remake limited editions, the text is engraved and filled with lacquer. And the dial has a sandwich construction, consisting of a lower dial plate covered with luminous material and an upper plate with cutouts for the hour markers.
The case is polished steel and 47 mm in diameter, a high, domed Plexiglas crystal. Though it appears to be a simple form at first glance, the case is carefully shaped, especially in the lugs and flanks. It is obviously made in two steps, first by stamping out the rough form, and then milled to get the details.
Visible on the back is the P.3000 movement. Though finished simply and mechanically the P.3000 has features that point towards stable, accurate timekeeping, including twin barrels and a large, free-sprung balance wheel.
Notably the Radiomir 1940 Marina Militare features a newly developed leather strap that has the OP logo stamped on both ends of the strap – it looks silly but fortunately Panerai straps are a breeze to swap with thousands of options available.
The Radiomir 1940 Marina Militare is a special edition of 1000 numbered pieces with a price of US$10,100. Panerai typically has a habit of making new editions based on successful, ostensibly limited models, and it remains to be seen if this Radiomir 1940 will be a one-off.
