9. Blancpain 1735 Grande Complication – $800,000
Even if it didn’t happen to be one of the most expensive wristwatches ever made, the Blancpain 1735 Grande Complication would still be seriously cool for its name alone. Don’t be fooled however as it isn’t just a clever name to score brownie points – it’s more of a very accurate description of what this particular timepiece is. After all, inside the thing are more than 750 handmade components and parts, which in turn make it one of the most complicated watches ever produced.
