One depth gauge and two Ref. 3646 watches @ Christie’s

by on Apr.13, 2016, under Watch Point

Christie’s features two different Ref. 3646 watches an a “40 metri” depth gauge from Guido Panerai & Figlio in their upcoming auction on 16 May 2016 in Geneva (Sale 1413).

Rahmen_Bild_hoch_2016_Christies_Lot133_LPDG40_GLot 133: A “Luminor Panerai” depth gauge (case size: 70 x 90 mm) for 40 metres with anti-reflective coating. The back of the depth gauge is signed “OFFICINE PANERAI · FIRENZE · BREVETTATO”, the steel GPF buckle, sewn to the strap, is unsigned. The Guido Panerai & Figlio instrument is accompanied by a heavy, stainless steel knife for underwater works, made by Galeazzi (La Spezia).

Similar depth gauges in various versions (aimed for proper use in different depths depending on the underwater activities) are featured in our new book “The References” (second volume / 1950’s-1960’s) in chapter XI (page 1314-1367). An identical “40 metri” depth gauge is shown on page 1364-1366. A similar Galeazzi knife with tool grip has been introduced earlier here.

Rahmen_Bild_hoch_2016_Christies_Lot134_KSLot 134: This watch has been added recently in our database. New to the market, representing another typical “Kampfschwimmer” of the Ref. 3646 / Type D number group with anonymous sandwich dial. The inner caseback engravings which bears the Rolex SA stamp, reference and case number, in combination with the Rolex Cal. 618 / Type 1 movement, are matching our database criteria for watches of the Reference 3646 / Type D number group.

Watches of the Ref. 3646 / Type D are featured in our new book “The References” (first volume / 1930’s-1940’s) in chapter II.IV (page 398-531).

Rahmen_Bild_hoch_2016_Christies_Lot135_RPLot 135: Again up for auction at Christies, the Ref. 3646 / Type C with “Radiomir Panerai” dial, as introduced in earlier postings from a past auction in November and December 2013. The outer caseback is engraved with a matriculation number of the Italian Decima Flottiglia MAS (short “Xa FLOTMAS No. 048”).

Watches of the Ref. 3646 / Type C are featured in our new book “The References” (first volume / 1930’s-1940’s) in chapter II.III (page 248-397).

We hope the depth gauge and the 3646 watches will find good new homes and remain surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]
