For a start it's being seriously underpriced from what I can see in the market. 2nd it's a classic - you will likely never see it's kind again. 3rd if you want a 5712/1a I would keep saving until you can afford both. A used 5712/1a can be sent back to Patek for refurbishment and will come back like new for a lot less than a brand new 5712/1a. It makes the target a little closer and worth being patient and waiting for.
