Alternatively, my local watch shop sells this "special" jewellery box made specifically for watches (It hold 12 watches, and costs $250) I like it as it has a glass top and I would be able to see my collection at a glance, but it also means storing them with the bands and clasps done up, so they are shaped round iykwim, not stored flat. I like the idea of storing them flat better. (They all have leather bands)

You can buy this sort of thing much more cheaply on Oz eBay.
