Hi Darryn - Discussing values is very much a part of this community. In fact there is a published price guide which is one of the main resources on the OTD site. If you have not already seen it, it is accessed from the home page. The guide price for a 1162 T "Siffert" is $3,000 to over $4,000 for a good one. Note that this is 2 years old. Prices have been higher than the guide but have also suffered more recently from what can be assumed to be the effects of the global recession.

In my opinion, the example you show with a MH bezel is worth the same as one with a Tachy bezel because the bezel can be change quite easily. Condition is difficult to asses from the small pictures but what we can see is that it has the correct early dial and hands, good bezel and a period bracelet which is correct for this watch. Sticking my neck out now, I would estimate that a good sample with all correct parts, not necessarily mint or even new old stock and certainly not a well worn sample would be worth...............around $4,500. Now you need to decide what it is worth to you.
