I was cleaning out my dresser drawer earlier in the day and I came across an old watch that I have forgotten for almost 10 years. About the watch, it is from a company called Mortima it is a French Made,dual crown sports watch. The dial is blue with 24 hour markings in white,features an internal diving bezel with calendar date with a small circular magnifyer at the 4-O-clock position in red numbers. The external bezel has tachymeter reading and can be turned. The crown at located at the 2-O-clock position sets the internal diving bezel. While the other is a pull-crown located at the 4-O-clock position, sets the time. The watch case is massive around 40mm excluding the crown. The strap size is 20 mm. I have an aftermarket stainless-steel bracelet mounted. The mineral crystal and the watch case is scratched,but the manual wind 21 jewels movement seems to be keeping time. Most watches have either painted or applied logo on the dial. Mortima has a small painted chicken located above the name of the watch. The style of the watch resembles the 1969 Seiko 6139 Automatic Chronograph. I am guessing that the age of watch must be near 40 years old. Last edited on Mon Mar 24th, 2008 01:49 am by Simon_Leung |

I found out that my Mortima is not the usual 21 Jewel manual wind movement. It is actually a 21 Jewel pin-lever watch. For those who are Horologically Literate: The Roskopf Movement, named after Georges Frederic Roskopf (1813-1889). His intention was to build a quality watch that was affordable to the working men. Technical Specifications of Pin-Lever for those too young to remember: A Pin-Lever or Pin-Pallet Escapement, is a lever escapement that is used in mechanical watches,which uses metal pins on the pallet of the lever,rather than the more expensive jewels. The pallet is the part of the lever that engages the escape wheel,which in turn transfers the stored energy in the mainspring to the balance wheel. Jewelled pallets can be made much smooter than metal pallets and therefore lose lot less energy due to friction. In short, watches with metal pallets wore out faster. Timex 21 Jewel Movement: For those of us who are old enough to remember Jim MacKay's from ABC Sports- commentator of the late 1960's - mid 1970's. He used to promote Timex Watches. Slogan: "Timex takes a licking and keeps on ticking." Yes, my friends at 3T those beloved Timex that once adorned your wrists were in fact, Pin Lever Watches. These were rugged watches that were inexpensive, a good example: Pick up a copy of Life Magazine from 1964 - 1966 with photos taken by the late English Photographer Larry Burrows. There you will find Vietnam Vets wearing Timex. From 1968 - 1975 most Vietnam Vets had switched to Seiko, because their Military Issue Hamiltons were either lost or damaged. The demise of Pin-Lever Movements is that they wore out faster than their manual wind and automatic counterparts and inaccuracy because to maintain a constant rate was often difficult. By 1980 The Quartz Revolution had dominated the market and put an end to all low-end watch movements. In the event of inaccuracies about this post, please feel free to contribute.
