Escapement mechanism is a device designed to maintain a constant average speed of the escape wheel, by allowing it to rotate to the desired angle at certain impulse of time. While doing that it simultaneously support the oscillations of the pendulum or balance spring, by compensating for friction losses and air resistance. 7 century long history of escapement mechanisms, from 13th century verge mechanism up to modern-day escapements that can be found in luxury watches, will be shortly presented. Through lives of famous clockmakers and their achievements in field of making escapement mechanism will be given a new insight in science of time keeping - horology.

  • Dynamics of Periodic Impulsive Collision in Escapement Mechanism
    Shock and Vibration 20 (2013) 1001–1010 1001 DOI 10.3233/SAV-130800 IOS Press Dynamics of periodic impulsive collision in escapement mechanism Jian Maoa,∗,YuFub and Peichao Lia aShanghai University of Engineering Science, Shanghai, China bTianjin Seagull Watch Co. Ltd, Tianjin, China Received 10 May 2012 Revised 25 January 2013 Accepted 13 April 2013 Abstract. Among various non-smooth dynamic systems, the periodically forced oscillation system with impact is perhaps the most common in engineering applications. The dynamical study becomes complicated due to the impact. This paper presents a systematic study on the periodically forced oscillation system with impact. A simplified model of the escapement mechanism is introduced. Impulsive differential equation and Poincare map are applied to describe the model and study the stability of the system. Numerical examples are given and the results show that the model is highly accurate in describing/predicting their dynamics. Keywords: Periodic collision, dynamics, escapement mechanism 1. Introduction Dynamics is an important branch of mechanical engineering. In the last century, the linear dynamics was well studied and understood. However, nonlinear dynamics is far from being fully understood because of its complexity and diversity [1]. Non-smooth dynamical system is a special category of nonlinear system. In practice, it is not difficult to find non-smooth dynamical systems, such as a hammer hitting a nail, a signal triggering an electrical circuit, and a disaster affecting the stock market. It is known that a typical smooth dynamical system can be described by an autonomous set of Ordinary Differen- tial Equations (ODEs) [2–6]. Newton method and Lagrange’s equation are two basic tools to model such dynamical systems.

Chapter 2 A Brief Review of the Mechanics of Watch and Clock According to literature, the first mechanical clock appeared in the middle of the fourteenth century. For more than 600 years, it had been worked on by many people, including Galileo, Hooke and Huygens. Needless to say, there have been many ingenious inventions that transcend time. Even with the dominance of the quartz watch today, the mechanical watch and clock still fascinates millions of people around the, world and its production continues to grow. It is estimated that the world annual production of the mechanical watch and clock is at least 10 billion USD per year and growing. Therefore, studying the mechanical watch and clock is not only of scientific value but also has an economic incentive. Never- theless, this book is not about the design and manufacturing of the mechanical watch and clock. Instead, it concerns only the mechanics of the mechanical watch and clock.

Some of them, like the unbreakable mainspring, dust, shock and water resistance, have long been achieved; even the lubrication-free watch may be achievable with Jaeger-LeCoultre’s ‘Extreme Lab’ concept.

    Press Release Patek Philippe, Geneva April 2021 Ref. 5236P-001 In-line Perpetual Calendar Patek Philippe introduces a totally new perpetual calendar with an innovative patented one-line display The manufacture has expanded its rich range of calendar watches with the addition of a perpetual calendar that displays the day, the date, and the month on a single line in an elongated aperture beneath 12 o'clock. To combine this unique feature with crisp legibility and high reliability, the designers developed a new self-winding movement for which three patent applications have been filed. This new in-line perpetual calendar premières in an elegant platinum case with a blue dial. As classic grand complications par excellence, perpetual calendars have always been prominently featured in Patek Philippe’s collections. In 1925, the Genevan manufacture presented the first wristwatch with this highly elaborate complication (movement No 97’975; the watch is on display at the Patek Philippe Museum in Geneva, No. P-72). Patek Philippe perpetual calendars offer a wide range of design elements with analog or aperture displays and dial configurations. Models with the famous self-winding ultra-thin caliber 240 Q movement, such as the Ref. 5327, can be recognized by their day, date, and month displays in three separate subsidiary dials. The self-winding caliber 324 S Q, which among others powers the Ref. 5320, exhibits another traditional face among the manufacture’s perpetual calendars. It features a dual aperture for the day and month at 12 o'clock and a subsidiary dial at 6 o'clock for the analog date and the moon-phase display.

  • The Escapement
    THE ESCAPEMENT Key to time Have you ever wondered why a mechanical watch goes “tick-tock”? The ticking is produced by the escapement, a strategic part that plays a key role in the movement’s measurement of time. This mechanism, consisting of several components, is a triumph of microtechnology. Its complex and exacting production process calls on all of the brand’s vast know-how and ingenuity. THE ESCAPEMENT “Tick”: a tooth of the escape wheel locks against one of the pallets. Then, released by the sweep of the oscillator – the strategic duo formed by the hairspring and the balance wheel – the pallet fork lets the wheel “escape”. The wheel continues to rotate and locks against the second pallet: “tock”. Only one-eighth of a second separates the “tick” and the “tock” that are so characteristic of mechanical timepieces. Synchronized by the oscillations of the hairspring and balance wheel , the pallet fork continues its infinite pendular beat against the oblique teeth of the escape wheel at a rate of 28,800 beats per hour – 14,400 “ticks” and just as many “tocks”. INTERACTION WITH THE OSCILLATOR Through its alternating beats, in interaction with the oscillator, the escapement is the “key to time” in the movement. It receives and regulates the raw energy from the mainspring and transmits that energy in impulses to the oscillator, which determines the division of time. Without the escapement, the mainspring would unwind in one go and release all its energy at once. And without the escapement to maintain the oscillations, the hairspring and balance wheel would rapidly lose their momentum and the movement would stop after a few minutes.

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.

Tweezers: Small parts can’t be handled well with fingers and it will be nearly impossible to service a platform Fig. 2 Important tools without using tweezers. The tweezers will have to be properly shaped at the tips so as not to eject the piece being held. Small parts can be shot large distances, and probably lost with improperly shaped tweezer tips.
