Help Wanted: Breguet watches owned by Thomas Engel
It may be 20 years since I lasted posted on WatchProSite but I am working on a project and thought maybe people much more expert than myself can assist a novice like me.
Please note: I am not a scholar of any stripe so I am treading in unknown waters and I may not have any idea of what I am talking about so please pardon any inevitable mistakes made relating to my project.
Please note: I am unfamiliar with the forum software so please forgive any formatting issues in my post.
Please allow me to thank anyone that muddles through the following and I appreciate any guidance anyone may offer me.
A small part of my project involves creating a list of Breguet watches once owned by Thomas Engel (TE) (note I am not referring to the Breguet-style watches made by Thomas Engel but the Breguet watches once in the Thomas Engel collection). Through various sources I have identified 31 Breguet watches and a Breguet carriage clock (No. 179) that once belonged to Thomas Engel. These sources included: Thomas Engel's autobiography, the 2001 Antiquorum sale, the 1976 MIH exhibition, Watchmaker to Kings and the 1964-1965 Christie’s sale of 60 Breguets once belonging to Sir David Salomons.
Certainly my list is incomplete; I have researched 50+ books, countless auction records, many, many articles from Alte Uhren, Klassik Uhtren, Chronometrophila etc. and I have been unable to answer the below questions and I hope someone/anyone may assist me. Note: I have contacted many people in the watch industry regarding my questions, some have been kind enough to respond but being a total stranger I am as expected ignored but even within the responses I did receive there was little consensus to the answers.
1. Christie's 1964-1965 Sir David Salomons sale: Edgar Mannheimer purchased all 20 lots from Part III of the sale (November 1965). Anecdotes suggest all 20 watches were purchased on the behalf of Thomas Engel (can this be verified?) My documentation finds for certain that Breguet Nos. 987, 3519, 3872 and 5047 of the Part III sale were owned by TE...the remaining watches from Part III are: Breguet Nos. 2556, 4760, 2758/417, 3012, 852, 3999, 4285, 3624, 4321, 119, 2183, 2687, 2934, 3625, 4047 and 2568 but I cannot locate any supporting documentation that these watches were owned by TE; if it can be verified that all the Part III watches were purchased by Edgar Mannheimer on the behalf of Thomas Engel then problem solved.
1b. Thomas Engel purchased one watch each from Part I and Part II; I know the watch purchased from Part II was Breguet No. 4238 but I have been unable to identify which watch from Part I was purchased by TE.
2. To the best of my knowledge Edgar Mannheimer and Seth Atwood split a set of Breguets (15 I think) owned by Dr. Halpern and the watches obtained by Edgar Mannheimer were then purchased by Thomas Engel; I am trying to find which Breguets they were.
3. Antiquorum 2001 Thomas Engel Collection Part II? 17 Breguets were sold in the Part I sale and to the best of my knowledge the Breguets scheduled for Part II were purchased as a group by private individual or museum; I am trying to locate a list of these Breguet watches.
4. Watchmaker to Kings: there are 30+ Breguet watches featured in the TE book "Watchmaker to Kings" I had thought all the watches in the book belonged to Thomas Engel but in the book Thomas Engel says: "My thanks go…to the numerous unnamed collectors who trustingly made their watches…available to me for reproduction" which suggests not all the Breguets in the book belonged to TE. Additional documentation suggests the following watches in the book did belong to TE: Breguet Nos. 164, 1320, 2292, 3519, 987 and 2782 leaving at least a score of watches without a verifiable owner.
Here is a list of references I have used so far in my project (and cluttering up my office) but these references do not to the best of my knowledge answer my current questions (at least not explicitly). Note the references are related to my project as whole not necessarily germane to the Breguets owned by Thomas Engel.
