Precision and Splendor: Clocks and Watches at the Frick Collection
ON VIEW IN THE PORTICO GALLERY PRECISION AND SPLENDOR: CLOCKS AND WATCHES AT THE FRICK COLLECTION January 23, 2013, through March 9, 2014 (extended, note new end date) Today the question “What time is it?” is quickly answered by looking at any number of devices around us, from watches to phones to computers. For millennia, however, determining the correct time was not so simple. In fact, it was not until the late thirteenth century that the first mechanical clocks were made, slowly replacing sundials and water clocks. It would take several hundred years before mechanical timekeepers became reliable and accurate. This exhibition explores the discoveries and innovations made in the field of horology from the early sixteenth to the nineteenth century. The exhibition, to be shown in the new Portico Gallery, features eleven clocks and fourteen watches from the Winthrop Kellogg Edey bequest, along with five clocks lent Mantel Clock with Study and Philosophy, movement by Renacle-Nicolas Sotiau (1749−1791), figures after Simon-Louis by a private collector, works that have never before been seen in New York Boizot (1743–1809), c. 1785−90, patinated and gilt bronze, marble, enameled metal, and glass, H.: 22 inches, private collection City. Together, these objects chronicle the evolution over the centuries of more accurate and complex timekeepers and illustrate the aesthetic developments that reflected Europe’s latest styles.

Continuation of the History and Progress of the Art of Watchmaking
293 XXIII.— Continuation of the History and Progress of the Art of Watchmaking. In a Second Letter from OCTAVIUS MORGAN, Esq., M.P., F.S.A. to Sir HENRY ELLIS, KM. Secretary. Read 28th Feb. and 14th March, 1850. MY DEAR SIR HENRY, % Pall Mall, Feb. 27th, 1850. MY former letter to you on " The History and Progress of the Art of Watch- making," and the exhibition of ancient Watches which accompanied it, having created some interest on the subject, I am induced to exhibit on the table of our Society some additions which I have since then made to my Collection, and which I will accompany with some observations on them, and such further particulars respecting the history of watches in general as I have been able to collect. I stated in my former letter that the first watches which were made had no fusee to equalise the power of the main spring, that improvement being a subsequent invention, but that there was some contrivance employed for producing that effect. This is mentioned in many works on watchmaking, but is nowhere accurately described, and the writers do not seem clearly to have known what it was. Nor do antiquarian collectors of ancient watches appear to have paid much attention to the internal construction of the examples which they have brought together. Berthoud, however, in his " Histoire de la Mesure du Temps," vol. i. p. 77, does give some description of it, and, speaking of the main spring, says, " It was soon perceived that, the action of the spring being much greater at the height of its tension than at the end, great variations in the watch resulted.

Any person(s) intending to use a part or a whole of the materials in the thesis in a proposed publication must seek copyright release from the Dean of the Graduate School. Ayvyai^A Thesis/ Assessment Committee Professor Hui，Kin Chuen (Chair) Professor Du, Ruxu (Thesis Supervisor) Professor Kong, Ching Tom (Thesis Co-supervisor) Professor Wang, Chang Ling Charlie (Committee Member) Professor Y. H. Chen (External Examiner) Abstract Abstract Mechanical timepiece is an intricate precision engineering device. Invented some four hundred years ago, mechanical timepieces, including watches and clocks, are fascinating gadgets that still attract millions of people around the world today. Though, few understand the working of these engineering marvels. This thesis presents a Virtual Library of Mechanical Timepieces. The Virtual Library is an online database containing different kinds of mechanisms used in mechanical watches / clocks. It uses 3-dimension (3D) Computer-Aided Design (CAD) models to demonstrate the working of these mechanisms. The Virtual Library provides an educational tool for various people who are interested to mechanical timepieces, including engineering students (university students and vocational school students), watchmakers, designers, and collectors. In addition, the CAD models are drawn to exact dimension. As a result, it can be used by watchmakers to validate their designs.

The dilemma or … Automatic watches with verge escapement, but without fusee! by Joseph Flores Comparative study of two automatic movements, of identical design, but signed and finished differently The verge escapement At the time of the first attempts in the 1770s to produce “watches which are wound by the movement of the persons who carry them”, according to the expression of the time, watches now known as “automatics”, the active brains of certain watchmakers were faced by a dilemma, whose explanation can make modern technicians smile. The question can be summarized as follows: Is it possible that a watch does not run while it is being wound? The answer these days is obvious, is it not, and yet at the time it was the case for the large majority of watches. Because practically all watches were equipped with the verge escapement, which is an escapement with recoil, and which could only function well with a part that has now disappeared: the fusee. And it is this fusee, which was essential, that caused the problem, … Except by modifying it or finding a device to replace it … Two questions are raised, and my answers given here: 1. Why does the verge escapement require a constant energy? 2. What is the problem arising from the fusee? Here are the explanations: The principle of operation of this escapement, the oldest of all, is known as “with recoil”. It should be understood that the phase of recoil we are considering occurs after impulse, and this kind of escapement has only 2 phases of operation: Impulse - Recoil.
