小白最近从eby上买了一块汉密尔顿怀表，表盘上汉密尔顿商标下方有TRAFFIC SPECIAL字样，表盘6点位置下方标着swiss，后盖写的宾夕法尼亚州兰卡斯特市，机芯写的汉密尔顿669，17钻，还标有swiss。请教各位大佬这块表的生产时间大概是哪个年份？是不是瑞士生产机芯不是汉密尔顿自产机芯？这块表是专供铁路部门的吗？我到手花了150美元有没有掉坑？谢谢各位，祝大家元宵节快乐！

查到一点资料，仅供参考！
In 1955 Hamilton introduced an entry level line of pocket watches called the "Traffic Special". That line was also used in the 1920's with certain size 16 pocket watches that were used on trollies and street cars. The Traffic Special line in the 1950's was priced at about 50% the cost of a railroad approved 992B model. They were intended for "working men" who wanted an accurate and easy to read pocket watch but without the price tag of a railroad grade model.
Two models were introduced in 1955, the Traffic Special I in a stainless steel case and the Traffic Special II in a yellow rolled gold plated case. Both are size 16 watches and feature a Swiss-made Hamilton 669 movement with 17 jewels. Apparently the only dial option was a single sunk heavy gothic design.

这就是一个科迪柏的机芯，里面已经是瑞士铁路表的形状了。

这不是闪电吗？……

这已经是被瑞士收购后的汉密尔顿了，其实和汉密尔顿已经毫无关系了，套牌表而已

请教古董怀表玩家老师，这是从eBay上找的一张992B的图片，这个算加装了避震吗？能否指出哪些地方算是有避震谢谢

请教各位大佬，美国华生645型机芯，21钻5方位调校，这种机芯属于什么档次？谢谢
