Let us talk about caliber P.5000 for a minute. It is a big motor: 2 mainspring barrels which you may easily see running in the two large jewels, providing eight times of running time at 3hz/21,600 vph. The mainspring barrels operate in series, pushing torque via a very classically arranged going train, with the centre wheel observable through a large cutout from the plate. I suppose technically speaking we’d have to call this a 3/4 plate motion as the third wheel bridge isn’t actually a bridge in the typical sense of the term, but instead caused by producing the cutout. That cutout in addition to the shape of the major plate around the equilibrium give a very aesthetically pleasing, but nevertheless pragmatic impact, which is totally suitable for what was, after all, initially intended to be an instrument lookout, plain and simple. The going train is arranged so the fourth wheel is exactly opposite the crown, which is exactly where you would locate it in a pocket watch, and if you want a tiny seconds dial in which it would have been in one of those Angelus pocket watch powered Panerais all you have to do is run the wheel pivot through the dial and place a hand on it (which was what Panerai did with the PAM 510).The balance, which is held in place by a very solid looking bridge, looks a little small for the motion but again, that is probably only because the motion’s so big; at 15 3/4 lignes, or just about 35.7 mm, it’s a pocket — observe as opposed to a wristwatch grade (unless you’re in the bigger-than-average-wristwatch business, which Panerai manifestly is). Overall, we think that it’s an impressive bit of work — we have used the word sturdy and sturdiness is very much the takeaway belief one has of the P.5000. Interestingly enough, incidentally, the P.5000 includes a free-sprung, adjustable mass balance, which is a really wonderful touch, especially at this price point — if you look closely at what seems like the regulator you will see that it is really not a ruler, but a stud carrier (in other words, the carrier to the stud to what the outer terminal of the balance spring is attached). The screws holding the balance bridge set up run through threaded collars onto the bridge and can be employed to adjust end-shake (the quantity of vertical “play” between the ends of the balance staff and the endstones of this shock-jewel assembly.
Panerai has announced a 500-piece limited edition Luminor Base Logo for the 15th anniversary of Paneristi, the brand’s enthusiast community website.
Paneristi is the Panerai enthusiast website, one that has created a community, in the truest sense of the word, dedicated to Panerai. For the 15th anniversary of the site, which was founded in 2000 by Guy Verbist, Panerai has created a limited edition Luminor Base Logo (PAM00634) with a blue OP at six o’clock. The third Paneristi edition – after the PAM195, PAM360 and PAM532 – the 15th anniversary PAM634 is a Luminor equipped with the hand-wound OP I movement (which is essentially a Unitas 6497) behind a solid case back. Notably the case back is a snap-on case back, a first for a Luminor, instead of the screw-down back typical of Panerai and other dive watches. Another feature traditionalists will bemoan are the spring bars for the strap, yet another first, instead of the traditional screwed bars synonymous with Panerai.
This is the first Paneristi edition that does not have a black PVD coated case, instead the 44mm case is polished steel with “Paneristi” engraved on the crown lever.
Another feature unique to this edition is the blue OP logo at six o’clock. Though this is the first for a dial, the blue logo has been used widely in the SIHH 2015 collection on straps. And the Super-Luminova on the dial is ivory, approximating the look of tritium-dial, Pre-Vendome Panerai watches from the 1990s. The PAM634 is limited to 500 pieces with a retail price os US$4200, which is slightly less than the US$4900 retail price of the PAM000 “logo”, the equivalent watch from the regular collection. Intended primarily for active members of Paneristi, the PAM634 order process can be found on the forum. Source: Paneristi Update June 29, 2015: Edited to include snap-on back and spring bars.
