Upcoming auction in November @ Dr. Crott

by on Okt.28, 2014, under Allgemein

The 2nd weekend of November will be interesting to follow the auction at Frankfurt’s Hotel Sheraton (saturday, november 15th). German auctioneer Dr. Crott will have their 90th auction with more than 600 lots. Earlier this year it was possible for us to see the two Vintage Panerai lots in advance for our reviews. Two Ref. 3646 / Type D “Kampfschwimmer” watches with anonymous sandwich dials will be up for sale (LOT 78 and LOT 79). You can find the reviews in this blog by using the tag function for “Dr. Crott”. Detailled information can also be found at the auctioneers website.

We hope that the watches find good new homes and that they remain surfaced in the Vintage Panerai collectors world.

Rare brass dialed “G-Bird” on auction at Antiquorum

by on Okt.18, 2014, under Allgemein

We got attention of another rare Vintage Panerai Ref. 3646, which will be up for auction: the particular watch, featured as a Ref. 3646 / Type G in our database of today’s existing Vintage Panerai watches, is within the smallest of the seven different number groups and will be auctioned at Antiquorum in Geneva, November 8th/9th 2014 (LOT 783). Detailled technical illustrations explaining the seven different groups within the Reference 3646 are published in our book “History1″ on page 72, as well as in our book “History2″ on page 550.

Features of the watch:
Reference: 3646 / Type G
Dial: “Kampfschwimmer”  (painted brass, anonymous)
Case number: 317526
Movement: Rolex Cal. 618 / Type 1 mod.

Find the illustrations of  Ref. 3646 / Type A – C casebacks here. You can compare the different inner caseback engravings in Ref. 3646 / Type D – G watches here.

Typical features of a Ref. 3646 / Type G watch are: the missing Rolex SA embossing on the inner caseback, bearing a plain center with the caseback number 317526 in the upper area, wich also marks the highest number in the Ref. 3646 / Type G number group (317488 – 317526) and can be called until today as “the last 3646″ recorded in our database. Another feature of Ref. 3646 / Type G watches is the center bridge of the movement (Rolex Cal. 618/ Type 1 mod.), which bears the “17 RUBIS FAB. SUISSE”, while earlier 3646 watches (Type A – Type D) bear the “ROLEX 17 RUBIS” engraved on the left of the center bridge.

All today known watches of this number group are equipped with a flat bezel as the dials are “California Dial” or the painted brass dial (not the typical Panerai sandwich construction dial, which needs a higher bezel to cover dial and hands).

This particular dial, a black painted brass disc with luminous material applied from the top, can be easily identified from a distance by its “closed” numbers 6 and 9, while on Panerai sandwich dials these two numbers are “open” because of the different production process.

Its a pleasure to see such a rare watch surfacing today being another full matching entry in our database, and one of the only less than ten watches known inside the Ref. 3646 / Type G number group. Watches of the Ref. 3646 / Type G represents the most anonymised versions of Ref. 3646 watches by their unsigned dial, unsigned inner caseback and unsigned movement (no Panerai or Rolex trademarks), in our understanding to hide the origins of these military tool watches, made in 1944.

We hope the watch will find a good new home and that it remain surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]

“Chronos” on Panerai: “Keeper of the Grail”

by on Okt.11, 2014, under Allgemein

German editor Jens Koch wrote an excellent story about the unique design of Panerai watches, following their roots from the past until today and in the future. The actual special issue of “Chronos” watch magazine (“Uhrendesign” / “watch design”) features his story on page 92-100.

By describing the history of Panerai from the early beginnings as a supplier of the royal italian navy until today’s models, photos of Vintage Panerai watches are featured (Ref. 3646 / Type D “Kampfschwimmer”, Ref. 6152/1 “Luminor Panerai” and a GPF 2/56 “Egiziano Grosso”). Koch explains in detail where Panerai today still use the DNA of the historic watches and how the brand can create new models by using the classic design elements today and in the future, as well as different case sizes and new materials.

Engraved “Kampfschwimmer” at Dr. Crott’s 90th auction

by on Okt.07, 2014, under Allgemein

Another rare Vintage Panerai Ref. 3646 / Type D is up for sale at Dr. Crott in their 90th auction on november 15th in Frankfurt (LOT 79). Recently captured some photos of the watch, bearing a rare and unique “Kampfschwimmer” engraving, featuring the initials of the first owner (“VK” for Valentin Kohlmann), year of service (1944) and the number of the task force he belonged to (“Meeres-Kämpfer 11. Einsatzgruppe”).

The watch has been delivered to the auctioneer by the veteran’s grandson, accompanied by a rare compass (black 54 mm case, solid lugs, unsigned), photos of Valentin Kohlmann during his service in WW2 and a documentation compiled by his family.

Features of the watch can be lined-up as the following: the aged plexi bears very fine cracks in the outer area near to the bezel, the blued steel hour and minute hand are both coming with the complete luminous material, the four numbers and eight markers of the anonymous “Kampfschwimmer” sandwich dial from Panerai appear in various colors reaching from yellow to orange. The number one wear-and-tear part, the winding crown, has been replaced by a non-screw-down-crown. The original “neck” and the tube for holding a screw-down-crown (Type 11 or Type 13 matching the thread of the tube) are still present.

Once opened the engraved caseback, the engine of the watch can be observed: the typical Rolex Cal. 618 / Type 1 movement without incabloc shock protection, the typical decorations on bridges and the “ROLEX 17 RUBIS” engraving on the center bridge. The balance cock is engraved with the S-F / A-R regulation device.

A view onto the fully decorated inner caseback shows the Rolex SA embossing in the center, reference number 3646 and individual case number below, which is recorded in our database in the group of Ref. 3646 / Type D watches.

Features of the watch:
Reference: 3646 / Type D
Dial: “Kampfschwimmer”  (sandwich, engraved)
Case number: 2604XX
Movement: Rolex Cal. 618 / Type 1

Similar watches of this type with anonymous “Kampfschwimmer” sandwich dials are featured in our books “History1″ (chapter II) and “History2″ (chapter V and chapter VII). An identical compass is featured in our book “History2″ on page 598, 600 and 601 (chapter VI).

We hope the watch will find a good new home and that it remain surfaced in the Vintage Panerai collectors world.

Just because… “volcano dome”

by on Sep.12, 2014, under Allgemein

Captured the domed shape of the plexi on this Ref. 3646 / Type D “Kampfschwimmer”. Slightly above the bezel, the “volcano dome” starts its smooth rounded shape from the lower outside to the higher center. Ref. 3646 watches have been produced over several years with different shaped plexi glasses. Another known shape is the flat centered version with a stronger curved outside area (see this Ref. 3646 / Type C “Radiomir Panerai” to compare / see this Ref. 3646 / Type D “Kampfschwimmer” to compare).

As the plexiglass was, aside the onion shaped or tubular shaped winding crown, one of the most damaged and naturally worn off part of these watches, spare plexi glasses replaced the initial plexi glasses. Its great to see another watch which comes still with its original “volcano dome”.

Another Vintage Panerai Ref. 3646 / Type D with a similar plexi is featured in our book “History2″ on page 632 / chapter VI.

Sneak Preview of a Ref. 3646 / Type D “Kampfschwimmer”

by on Sep.06, 2014, under Allgemein

Got the chance to stop by at auctioneer Dr. Crott in Mannheim / Germany for taking a close look at yet surfaced Ref. 3646 / Type D “Kampfschwimmer”, which will be auctioned on saturday, november 15th in Frankfurt (LOT 78).

The watch is filling another place of a piece in the big Vintage Panerai puzzle, matching our database criteria in the group of the watches of the Reference 3646 / Type D. It has been recently delivered to the auctioneer being a heirloom of a german watchmaker’s family.

The front view shows the anonymous “Kampfschwimmer” sandwich dial and the bright blue steel hands with their original luminous material (partially off). Small cracks in the plexi are proof of age of the “volcano dome” shaped plexi.

Also the aged numbers and markers of the dial in different colors (from yellow to light orange / amber) are a typical feature of 3646 / Type D watches and can be found on many others. The screw-down caseback of the watch is plain (without individual engravings).

The inner caseback shows the – typical for the Ref. 3646 / Type D criteria – Rolex SA stamp, reference number and case number and has a fully decorated finish. The engine of the watch is the Rolex Cal. 618 / Type 1 movement.

Typical for this type of movement is the “ROLEX 17 RUBIS” engraving on the center bridge. As usual on Rolex Cal. 618 movements used in watches of the Reference 3646, the balance cock bears the S-F / A-R regulation device.

Features of the watch:
Reference: 3646 / Type D
Dial: “Kampfschwimmer”  (sandwich, engraved)
Case number: 2606XX
Movement: Rolex Cal. 618 / Type 1

The new owner of this watch may decide to change the actual non-screw-down replacement crown with tubular shaped “Oyster Patent” crown (Type 13) or – with some luck – with an onion shaped “Brevet +” crown (Type 11). The “neck” of the cushion shaped case still exists and a good watchmaker should be able to place a tube into it to get a screw-down crown from Rolex on it.

Similar watches of this type with anonymous “Kampfschwimmer” sandwich dials are featured in our books “History1″ (chapter II) and “History2″ (chapter V and chapter VII).

We hope the watch will find a good new home and that it remain surfaced in the Vintage Panerai collectors world.

Taking a close look at a Ref. 3646 / Type C… “Red Radiomir”

by on Jul.23, 2014, under Allgemein

Spot on “Red Radiomir”! Only a few watches have been aged in the way that the black color of the dial faded to grey and the luminous “Radiomir” of the four numbers 3, 6, 9 and 12, as well as the eight 5-minutes-markers turned into a deep and intensive red color. More info on this amazing 3646 / Type C watch has been published earlier  and back in 2010.

A similar watch with dark red aged “Radiomir Panerai” dial is featured in our book “History1” in chapter I.

The Rolex Cal. 618 movement – engine of the 3646

by on Jun.24, 2014, under Allgemein

Used in Ref. 3646 watches from Type A to Type G, the Rolex Cal. 618 / Type 1 movement comes without Incabloc shock protection.

Typical for this non-incabloc version is the serif font for the letters A-R (french) and F-S (english) engraved on the regulation device. The screwed off caseback next to the case shows the decorations on the inner caseback (completely decorated). More Information about the different finishings on inner casebacks of 3646 watches can befound in our book “History1″ (page 166-167) and in our book “History2″ (page 546-547).

See also a comparing between the Rolex Cal. 618 / Type 1 and the Rolex Cal. 618 / Type 4 movement).

The clean face of a 3646 “Kampfschwimmer”

by on Jun.14, 2014, under Allgemein

Reduced to the max, simple, clean – the design of the Panerai sandwich dial without the engraved “Radiomir Panerai” as it appears on Panerai watches used by “Kampfschwimmer” units during the 2nd world war.

The aged numbers and markers of the dial in different colors (from yellow to light orange / amber) are a typical feature of 3646 / Type D watches. The clean face of the dial -  just 8 markers, 4 numbers and 2 hands - glowed in the darkness to keep it’s operator “in time”. Waterproof. And of course accurate: functionality can be simple – and something which the users of these watches had to trust in.

This Ref. 3646 / Type D watch is featured in our book “History2″. Read more about the first owners and the missions in which it was used as an important underwater tool in chapter V.
