Sepia Saturday - The watchman

T1 is code for Turtle 1

When I saw the theme picture for this week I was very much surprised because I immediately recognized a member of the RSSSATP, you can tell by the protruding little fingers. As you can see he is closely watching a species of the Dermochelys coriacea. Beg your pardon, you don't know what RSSSATP stands for? That is the Royal Society for the Strategic Study of Advancing Turtles in the Pacific. Since you are apparently unaware of this important semi military organization, maybe I should explain their objectives. First of all I have to say it is a secret organization, a lot of hush hush. That is because of its strategic significance. Its membership is restricted to army and navy biologists and it is highly unusual to see a picture of a member in action. 
You may wonder about the pipe. Well, so do I but my guess is that this officer is a pipe smoker. On the other hand I wouldn't be surprised if the pipe, or its smoke, is related to the study he is carrying out. Smoke curtains and all that. Because rumour has it that the research of this eminent organization has to do with amphibious landings. You may know that certain turtles live in the sea but lay their eggs on the beach. The study aims at investigating the methods these turtles use to overcome the surf without capsizing. For this purpose certain marks have been applied to the turtle's shield. That is done to facilitate air reconnaissance.  I am afraid I can't give you any further details without being accused of all kinds of nasty things.
Despite the risk of revealing state secrets I will base my Sepia Saturday contribution on the wristwatch the officer is wearing. Although I am not a wristwatch wearer (what a word!) myself, I do have a few heirlooms. To be honest some of these objects have not yet reached that status yet but one day they will.

Bulova Accutron 1960

This Swiss watch dates from 1960. It is a very special watch because the movement is determined by a tuning fork. Rather than giving you the wrong info I quote from Wikipedia. "The tuning fork movement was a horological revolution.

Previously, electronically regulated timepieces were limited to some scientific instruments, being too large for a personal watch. The Accutron was also the first wristwatch precise enough to qualify for U.S. railroad certification." And if you qualify for the U.S. railroad...
You can see the tuning fork between the two electromagnetic coils at the top of the watch left. Unfortunately there is something wrong with my watch. When I activate the watch it runs way too fast. So if it has to become a valuable heirloom I need to have it repaired.
The next timepiece is a pocket watch. It was given to me by my Aunt Jo. Aunt Jo was married to Johannes Frederikus Miebies (1899-1958), the son of my grandfather's brother and the previous owner of this watch.

Omega pocket watch 1913

I tried to date this pocket watch by comparing it with Google images. But no success there. Fortunately most Omega pocket watches have been numbered. This one carries number 4322892. That means it has been manufactured in 1913. So this year it is exactly 100 years old! It is also Auntie Jo's birth year. Coincidence? I don't think so but I'll ask her, she's still among us!

Smiths 30Hours

Smiths English Clocks Ltd was operational between 1931 and 1979. I think this model was manufactured during the 50's but I am not sure. Apparently these 30 hours clockworks were a specialty of Smiths. I don't know why the clocks were 

limited to a 30 hours running time. There might very well be a technical reason for that. 
Neither do I know when 30 Hour mechanisms were made. But no matter when that was, it's still running like you know what. It produces a nice ticking noise for easily more than 36 hours.
My clock is integrated in the showcase like cabinet shown here. When we bought it the antique dealer said the cabinet was English made. For all I know it could have been Turkish as well. I am not an expert in these matters but possibly one of the Sepians is. 
The last watch on display here is another pocket watch. According to my mother it belonged to her father Gerardus Theodorus de Langen (1888-1967). It is a watch that puzzles me because I am not even certain in which country it has been made, Switzerland or France. It is a Judex montre de precision (precision watch) with serial number 997331.

Judex pocket watch possibly 1920-1930

I saw another Judex pocket watch with a similar diamond shaped decor. That one was made between 1920-1930. Unlike the Omega shown above this one is running fine.

When I opened the back of the watch there was another surprise: the original warranty. It mentions the serial number and the fact that the case is made of silver (argent). The term épreuve de réglage means 'test' or 'control'. But the nature of the test is not clear to me. I noted that the watch-glass has been replaced by plastic. At least I assume it has been replaced because I don't think plastic was used for the original. Maybe grandpa inadvertently dropped it somewhere.
Well, this is it. I am running out of ticking devices. It's time for you to watch other stories. So hasten yourself to the Sepia Saturday site. But be careful, don't turn turtle!
