Pocket Watch Case

RARE AND HISTORICALLY INTERESTING! CAPTAIN’S DUAL TIME ZONE WATCH WITH A VERY RARE ALUMINUM CASE, MARKED WARRANTED ALUMINUM. There was a time in the mid 1800′s when Aluminum was more precious and costly than Gold. History has Napolean III serving his most honored guests with Aluminum tableware, while the less exalted attendees had to make do with silver! The use of Aluminum in Watch Cases is rare indeed. The use of this Metal in a Seafaring Timepiece is of interesting Historical note because of Aluminum’s oxidation resistance. This is the only timepiece of this type I have ever encountered. It has a “Warranted Aluminum” stamp that indicates the Material was still rare when the case was produced. The Movement dates to Ca. This would have been in a transitional period when Aluminum was probably still more precious than silver, but not ultra rare and valuable. The cost of producing Aluminum dropped rapidly as electrostatic collection methods were improved throughout the 1860′s and 70′s. With the advent of more modern electricity generation the cost of production and thus the cost of the metal itself dropped to a level where commercial industrial uses were possible.
