Opened Ref. 6152/1 with solid caseback and dust lid – the Rolex Cal. 618 / Type 4 movement bears the typical markings for this type of Vintage Panerai watches. You can see an overview of the three different inner caseback markings of the “615ers” here.

This Vintage Panerai watch is featured in our book “History1″. You can read more about its first owner Mario Arillo in chapter IV, page 227-391.

Opened Ref. 6152/1 with solid caseback – bearing the typical markings for this type of Vintage Panerai watches.

You can see an overview of the three different inner caseback markings of the “615ers” here.

A nicely captured Vintage Panerai Ref. 6152/1 “Luminor Panerai” in the focus, showing an orange coated plexi. The side area of the plexi shows markings from a rotating bezel, which was once attached but did not “survived” until today. Aside this watch, other today existing watches with similar plexi glasses to carry a rotating bezel are filed in our database. The watch is equipped with “double pencil” hands (“sharp pin” version). Under the non-engraved caseback and dust lid, the engine of the watch is a typical Rolex Cal. 618 / Type 4 movement with 17 Rubis and Incablock shock protection.

Today, the reason for the transparent orange coating on the plexi isn’t known. Either it has been applied for a practical reason (anti-reflecting or camouflage) or the color of the coating has been aged and so changed its color over the years, adding up this orange patina.

A side-by-side view onto two Ref. 6152/1 Vintage Panerai watches. While both watches with the legendary crown protecting device using a “Luminor Panerai” dial, their movements are different: The left Ref. 6152/1 is powered with an Angelus Cal. 240 SF (8 days) movement (15 Rubis and Incabloc shock protection, signed “JUIN .61″) and the right Ref. 6152/1 is powered with a Rolex Cal. 618 / Type 4 (17 Rubis and Incabloc shock protection) movement.

Noteable is also, that the opened casebacks are different too: on the caseback of the watch with Angelus movement, the Rolex stamp has been milled off, while the watch with Rolex movement is bearing the typical 6152/1 stamp in the middle of its inner caseback.

A rare Ref. 6152/1 “Luminor Panerai” infront of the camera. Produced by Panerai for the italian state police divers (“Sommozzatori della Polizia di Stato”, founded in 1958). It bears a rare engraving on the backside of the case: “P.S. 02”.

Today other type of engravings on the casebacks of some few Vintage Panerai watches are known from the italian helmet divers (“S.M.Z.”) and combat swimmers of the Marina Militare (“M.M.”), aside italian police institutions as the Guardia di Finanza (“G.F.”) and Carabinieri (“C.C.”). Some examples for the italian fire brigades (“V.F.”) are known too.

It is interesting to see that Panerai has been a trustful supplier for different italian divers – military and also civil units.

Cleaning up my Ref. 6152/1 for the next photo session of our book “Vintage Panerai – Watches with History”. Took off the strap, removed dust and dirt on the case, between the lugs and along the crown protecting device, checking its Rolex Cal. 618 / Type 4 movement. Put back the original strap with G.P.F. Mod. Dep. buckle… Ready.

Tried to catch some nice views on my Vintage Panerai watches today. The Rolex Cal. 618 / Type 1 (Ref. 3646) and Rolex Cal. 618 / Type 4 (Ref. 6152/1) movements are doubtless a part of the Panerai DNA. Strong machines, which are still keeping perfect time after many years of use.
