Splash In the Past: Diving using the Panerai Luminor Marina 1950 three days Acciaio

Within this watch test feature in the WatchTime archives, a frogman re-results in a dive in the 1950s to check the in the past inspired Panerai Luminor Marina 1950 three days Acciaio.

Whenever you take a look at Panerai watches which have been modeled on their own historic predecessors, and, like them, have stationary bezels and leather straps, do you question if frogmen really used the initial versions on their own dives? In the end, a rotating bezel and metal bracelet or rubber strap are actually considered mandatory for watches for diving.

Obviously, there’s ample proof that military frogmen really did put on these early Panerais. What were their missions like and just how made it happen feel to participate them? We looked for clues by having an experienced frogman who is part of the Historic Diving Society, an worldwide organization focused on preserving and protecting diving heritage. He donned a classic-fashioned diving suit and introduced along vintage equipment. Also, he introduced across the Panerai Luminor Marina 1950 three days Acciaio, which looks just like a Panerai watch in the 1950s, therefore we could revive a bygone era and experience the way the frogmen of yesteryear may have felt.

The Panerai Luminor Marina 1950 three days Acciaio that people required on the dive looks just like its ancestor, having a 47-mm situation along with a crown protection bridge.

Panerai made its first prototype watches for diving for Italian military divers in 1936. Timepieces, which grew to become referred to as Radiomirs, entered production 2 yrs later. Within the mid-1950s, Panerai introduced a brand new version having a curved, crown protection bridge. It grew to become referred to as Luminor. Until 1993, Panerais were offered simply to the military. Before this, collectors who wanted a Panerai watch needed to locate one in an auction.

The Panerai Luminor Marina 1950 three days Acciaio that people required around on the dive looks just like its ancestor. Such as the original, the timepiece includes a 47-mm situation along with a crown protection bridge. The little seconds subdial often happens towards the earlier model: around 1956, Panerai replaced the watch’s Rolex hands-wound movement, which in fact had no seconds hands along with a 36-hour power reserve, by having an Angelus caliber which had a little-seconds display as well as an eight-day power reserve. Although our test watch includes a power reserve of 72 hours, we're feeling that it is greater than sufficient for any hands-wound watch.

The diver who supported us on the dive, Jens H?ner, is really a trained frogman and mine clearance diver that has set depth records both with and without equipment, together with a scuba dive to some depth of 240 meters. He's explored underwater caves and submerged shipwrecks. We collaborated with him along with the Historic Diving Society to restage a unique scenario: to take a dive outfitted similar to the military divers from the 1950s and ’60s. And before he required the plunge, he strapped on the test watch, a Panerai Luminor that suits its historic predecessor in virtually every detail.

Then as now, it’s essential for a military diver to utilize a “rebreather,” that is a closed circulation diving device. It can make a lengthy dive possible, while assuring that no telltale bubbles rise towards the surface and provide away the diver’s location. Unlike recreational divers, a military frogman doesn’t have a large tank filled with pressurized air with him he carries rather a smaller sized tank filled with oxygen that, despite its smaller sized volume, enables him to remain underwater for 2 to 3 hrs. The environment he exhales is given soda lime within the device to avoid co2 retention. However the drawback to this technique is the fact that because the depth increases, breathing molecular oxygen at elevated partial pressures can rapidly result in oxygen poisoning. For this reason divers using these units can securely descend to simply about six meters, a depth that’s relatively shallow yet great enough for many military missions. These divers typically go swimming for lengthy stretches, remaining under water and therefore from sight, and just after they’ve swum well past enemy lines will they come ashore to conduct reconnaissance or inflate a bridge.

Knowing his location is vital for any frogman. A bathometer or depth gauge, a compass, a sketch from the coastline’s contours and, obviously, a wrist watch are essential equipment for him. For the dive, additionally to his watch, H?ner strapped onto his forearm a musical instrument to survey the shore. This device enables him to collect and record cartographic data in regards to a stretch of shoreline, information you can use to aid amphibious landing operations by frogmen on subsequent missions. We made the decision to complete without another items transported by frogmen, for example weapons and explosives.

The Luminor dial includes a lower disk bearing the luminous substance as well as an upper disk that the indexes and numerals happen to be eliminate.

Whenever you consider the listing of tasks done by military divers who usually go swimming at shallow depths for lengthy amounts of time, you can observe why a rotating bezel for presetting the dive time isn't necessary - even if this function debuted as soon as 1953 with the development of the Rolex Submariner. Frogmen used Panerai’s watch mainly at depths of six meters or fewer, on missions that lasted several hour. Unlike much deeper dives, these excursions don't require decompression stops, so a rotating bezel isn’t of great importance and use.

The timepiece offered much more like a navigational instrument: for instance, a diver could cover an incomplete stretch leading toward his ultimate destination by swimming along a preset compass course for any predetermined period of time. There wasn't any practical method to appraise the swimmer’s speed, so minutes markings weren’t essential.

Most military missions required place - but still occur today - under cover of darkness, so brightly luminous dials are essential. Panerai contributed greatly to improving night time legibility by developing its very own light-emitting luminous substance for that Radiomir and then replacing it within the Luminor having a similarly vibrant but less strongly radioactive material. The sandwich-style dial was essential to elevated legibility. The dial includes a lower disk bearing the luminous substance as well as an upper disk that the indexes and numerals happen to be eliminate. This permits Panerai to make use of more luminous material than could be possible when the numerals were simply printed or colored to the dial. The process, that is still employed today, cannot be employed to create luminous indexes for that individual minutes: cutting 60 strokes in to the upper disk would jeopardize the dial’s durability. That is why the markings were, but still are, limited to five-minute times, but they’re sufficiently precise for lengthy missions.

The sandwich-style dial can also be the reason behind the distinctive open form of the numeral “6”: its inner part should be linked to its outer part. To create a virtue of the necessity, and to produce a handsome dial despite functional limitations, is really a task that may most likely happen to be achieved only by Italian designers.

Under water by fading daylight, the Luminor’s very is almost nonreflective and it is big dial is extremely readable.

We decided on a leather strap for the test watch, as opposed to a rubber one, that also has the watch, because Panerai’s original model were built with a leather strap. The instructions that include the timepiece specifically condition the leather strap may be used on dives, but we still needed to overcome our desire not to take this pricey strap in to the cold water. It’s surprising but correct that Panerai’s leather straps are as appropriate as always for immersion in water since the leather is almost untreated. Once the diver returns to terra firma, it requires some time for that strap to dry fully, but afterward it appears just as it did before its submersion. Extension pieces for divers were unavailable years back, therefore we chose a particularly lengthy XL strap that will accomodate the cuff of the diving suit.

Since H?ner has donned his diving suit, he begins smearing his face and hands with camouflage makeup, that was also utilized in the 1950s. Then he straps on his rebreather, a prototype produced by the German company Dr?ger in early ’60s. He pulls his diving mask round his mind. The mask dates in the era when Panerai was still being equipping Italian Navy frogmen. He then turns and approaches the river, walking backwards because that’s the fastest method to walk when putting on fins. He rinses his mask, slips his rebreather’s mouthpiece between his teeth, glances at his watch and slides quietly in to the water without departing the smallest trace of the air bubble.

Under water by fading daylight, the Luminor’s very is almost nonreflective and it is big dial is extremely readable, thus fulfilling its most significant requirement. Our frogman is well hidden because of the camouflage makeup and dirt, but his watch’s polished situation catches our eye. The initial models were equally shiny: we can’t explain why Panerai didn’t choose to provide them with a satin finish, which may have caused less glare and been less inclined to reveal the diver’s location. Can it be that Italian design got top of the hands here?

The timepiece is operated by the hands-wound, in-house Caliber P.3001. Having a diameter of 16? lignes (37.2 mm), it’s nearly exactly the same size because the original 16-ligne Angelus movement. Forgoing a regulator mechanism, the caliber could be finely adjusted by turning weight screws across the balance’s rim. This assures the balance spring can breathe freely. The total amount oscillates within robust balance bridge.

The movement’s adornments match the Luminor’s character. Probably the most eye-catching embellishment is really a rather technical-searching striped pattern, which runs in the same direction along the 3 bridges. It goes well using the unconventional blue engravings.

Panerai watches were very perfect for their military missions, while they wouldn't satisfy the standards of today’s divers’ watches.

A couple of special features distinguish the watch’s operation. Once the crown is brought out to the first position, the hour hands could be reset in hourly increments without having affected the positioning of the minutes hands. This really is convenient when you're traveling to a new time zone or resetting time early in the year and fall: you are able to reposition the hour hands without having to stop the minutes or seconds hands. Should you pull the crown to its second position, you are able to adjust the minutes hands - and also the hour hands together with it - within the usual manner. The seconds hands leaps to zero in this process, thus which makes it simpler to synchronize your watch having a radio time signal.

Older Panerai watches had none of those convenient features. Underwater legibility and water proofing were the watches’ primary benefits in individuals days.

Whenever you put on the suits and bear the gear utilized by frogmen decades ago, it rapidly becomes obvious what feats individuals amphibious fighters accomplished with nothing more than strength. Panerai watches were very perfect for their military missions at shallow depths and throughout many lengthy hrs, while they wouldn't satisfy the standards of today’s divers’ watches. Yesterday’s frogmen may get by without rotating bezels. So that as our test demonstrated, the leather straps used in those days were quite able to associated a military diver. The historic watches aren’t only functional, but additionally handsome: then as now, we are able to thank Italian the perception of their rugged visual appearance.
