百年的芝麻鍊使用上還是自己用點心照顧比較省心點^^

對於百多歲的芝麻鍊,尤於百多年前左邊的發條筒跟右邊的寶塔上鍊柱心使用磨損,常常會讓兩邊的柱狀筒失去水平,芝麻鍊拉緊下右邊的寶塔輪就會呈現左上右下的拉扯狀態,然後就會看到左邊的發條筒上的芝麻鍊第二圈爬上第一圈起始勾鍊條的窘況
,這點使用上上發條在幾次以牙籤插入右邊寶塔輪調整寶塔輪的角度後,終於在芝麻鍊釋放完不在呈現第二三圈爬上第一圈的窘狀,
,要維護這種狀況就是在上發條時不要讓芝麻鍊全上完,留第二圈在第一圈的下方,也算是一種對古董懷表的維護之道

學習了!

兩件都很贊外殼還是?琺瑯彩繪的
像這種調快慢據賣家是說數字越小越慢,只是像這盤子上也沒看到可以對準的箭頭,另外很奇怪的是調快慢的指針好像都被截短(或斷掉了)

後來找到關於這種芝麻鍊調發條的鬆緊的裝置很原始的發明,google翻譯大約是這意思
調節器是彎曲齒條和小齒輪的形式。機架的一端帶有兩個包圍螺旋平衡彈簧的路緣針。沿著平衡彈簧移動這些路緣針會改變其有效長度，從而改變手錶的速度。通過將鑰匙施加到從小齒輪突出的正方形並轉動它來移動機架。順時針轉動小齒輪可將路緣銷從螺柱上移開，縮短彈簧的有效長度，使手錶運轉更快。逆時針轉動小齒輪可將路緣針朝向螺栓移動，使彈簧的有效長度更長，手錶運轉較慢。
Tompion's or Thuret's regulator

This is probably the earliest form of watch regulator. Thomas Tompion made the first English watches to have a balance spring in 1675, as part of Robert Hooke's efforts to show that he had invented the balance spring. A watch made by Tompion and presented to King Charles II was inscribed "Robert Hooke invent. 1658. T. Tompion fecit, 1675". This watch is lost and the exact form of the balance spring is not known, but later Tompion watches have the form of regulator shown here, which as a consequence is often called Tompion's regulator.

Tompion's or Thuret's regulator

The regulator is in the form of a curved rack and pinion. One end of the rack carries two curb pins that embrace the spiral balance spring. Moving these curb pins along the balance spring alters its effective length and so the rate of the watch. The rack is moved by applying a key to a square projecting from the pinion and turning it. Turning the pinion clockwise will move the curb pins away from the stud and shorten the effective length of the spring, making the watch run faster. Turning the pinion counter-clockwise will move the curb pins towards the stud, making the effective length of the spring longer and the watch run slower.

Usually you can't see the rack and pinion, but a silver disc mounted on the arbor of the pinion is visible, set into the top plate. This plate is engraved with arbitrary numbers that are helpful as a relative reference when making adjustments.

In fact, it seems that although Hooke had been working on applying springs to watch balances for some years, it was Christiaan Huygens of the Netherlands who first came up with the idea of using a spiral balance spring, and it seems that watches with spiral balance springs and the type of rack and pinion regulator shown here were made by Thuret in Paris for Huygens before than Tompion's watches, so this should really be called Thuret's regulator, but I doubt that this will happen!
