To butcher a turn of a famous quote from the movie 'The Treasure of Sierra Madre', I feel it is important to take a stab at the most queried question about Hamilton 9812's and that is 'WHAT ARE THEY WORTH'?
Well to be honest - 'I don't know' or maybe an even better hackneyed retort 'Whatever somebody will pay' is the most accurate response I can offer. I have seen 9812's sell for under $20 to well over $200 depending on the condition, whether they have an imprinted serialized case, a unique highly detailed dial design, and exceptional documented provenance that is in high demand.
As a collectible, the watches generally offer a price point that most can take advantage of without breaking the bank unlike Rolex, Tag and the other elite brands. Typically these Hammy's become part of a collection of many varied objects centered around a corporate logo, brand, or theme. Since they were typically only produced for a short time and small corporate-specific runs, scarcity is an issue for some logos and dial types. In any given month you may find several 9812's available for sale but the odds that you will find a SPECIFIC 9812 design is fairly rare. So if you are unwilling to wait or don't have time to hunt a known example down, expect to pay considerably more to get what you want, when you want it.
In general terms, MOST of the time a generic 9812 in reasonable condition (a few scratches, not mint, no box etc.) with a basic logo dial and replacement band will cost $15 - $70. Obviously more documentation, provenance on why it was awarded and to whom, mint with advertising, box, warranty card - you know the drill - expect prices to easily exceed your hopes to the tune of $200 - $300. Note that in ALL examples, the movements are nearly identical. As simply a watch, the 9812 is a very attractive and excellent quartz, well constructed timekeeper.
