“Tempus fugit.” Macro Photography Anatomy of a watch #169

1. Hamilton No. 992 railroad model

Let me introduce you to my treasured pocket watch manufactured circa 1930’s. This is a railroad grade watch still running strong. It is the marvel of mechanical efficiency representing the pinnacle of the now defunct American watch-making industry. The 992 was manufactured to the highest quality of construction complying to the rigours of railroad service  by the legendary Hamilton Watch Co., Lancaster, Pennsylvania.

The last cleaning-oiling- adjusting was done by Mark Siriani master watchmaker, Kane, Pennsylvania in March of 2009. In addition he replaced the chipped roller jewel and adjusted the stuff/balance wheel.

You see on the 1st picture a double sunk, partial Montgomery porcelain dial and a fine set of original deep blued railroad approved hands. The case is made of 10 Karat rolled gold.

Here is part of the inscription of the watch on the nice damaskeened plate.

Hope you enjoyed the dissection of this fine timepiece. Let me know if you have an old pocket watch and still using it!

Macro photography

Macro photography is fun and a whole new world is waiting for you to discover it.

The first two photos were taken by a Nikkor 105mm 2.8 Ai-S  micro manual focus lens on a tripod at aperture f/8 and f/5.6 respectively under natural light. The last three shots were taken by the same lens at aperture f/16,  mounted a Nikon No. 4T close-up lens in front of it. The 4T is a doublet, that is a two-element, achromatic design for better image quality.

Always use a lens in manual focus mode on a tripod when doing macro photography! Focus very carefully to the primary detail of your subject because the depth of field is very narrow! Here are a couple of  great websites for introduction to macro photography:

    • Thank you, Kim. Yes, this watch is a mechanical masterpiece still working strong after 80 years or so. Trains were coordinated and run on time with help of this little jewel. No plastic, no quartz, no battery. Not made in China. Just impeccable American craftsmanship at its best.
