Serial numbers are often used in network protocols. However, most sequence numbers in computer protocols are limited to a fixed number of bits, and will wrap around after sufficiently many numbers have been allocated. Thus, recently allocated serial numbers may duplicate very old serial numbers, but not other recently allocated serial numbers.
For instance, a Rolex watch with a serial number starting with 28000 was produced in 1926. Reference 6234 has three smaller sub-dials, to mark the passage of seconds up to 60 seconds (at the 9 o'clock position), minutes up to 30 minutes (at the 3 o'clock position), and hours up to 12 hours (at the 6 o'clock position); all of these match the ...
Many of these are very similar to watches made at the time by the Hamilton Watch Company.

In its span, it encompassed metal and plastic cased watches with both mechanical and quartz movements. [2] The 46374 replaced the MIL-W-3818, reducing cost and inheriting the dial from ...
The first example of this practice was an early 1937 order for two-hundred Avro Manchester bombers; which were allotted the registration numbers L7276-7325, L7373-7402, L7415-7434, L7453-7497, L7515-7549, and L7565-7584, covering a range of 309 possible serial registration numbers, and thus making it difficult for an enemy to estimate true ...
