In the US titanium watches are normally only available in “Flagship” Apple Stores, which are the larger stores in the busier more populated areas. The smaller Apple Stores don’t stock titanium watches. I’m not sure if it’s the same way in Germany at all, but if you are near a big city then I would look at the larger Apple Stores there as those would be the most likely ones to have them.
However, in the US it seems that all the Apple Stores, including the ones that don’t stock the titanium watches do still have titanium watches on display. So if you want to see one in person before you buy it then here, at least, you can go into any Apple Store to see the watch.
Thank you! I know the Munich Apple store has them but never asked if they have one for sale. Will ask on Saturday. Delivery still 6.11-13.11
