Where to buy a diver's watch in Frankfurt

I am going abroad next Friday for a few days and at the last minute have been asked for a Diving watch - model Casio SPF60 or CasioSPF100. I have no idea where to find such an item. Can anyone please help? Thanks in advance if possible:)

try here.. http://www.megatime.de/uhren/sportuhren.htm maybe you can pay over the phone and ask for express delivery?

Our any decent jewellery or sport shop might have one...

There are at least three jewelers on the Zeil with large selections. You might even try Karstadt or Kaufhof..the latter has a wider selection.

There is a really nice dive-shop near Frankfurt. It's actually closer to Offenbach. You know where the Harley Factory is? It's right there - on Wächtersbacherstraße.

Here's the website: www.aquanaut.de

They are English speakers and some of the nicest folks in the area.

On the second floor of the SportArena at the Hauptwache there's a little dive shop tucked away in the right-hand corner as one comes off the escalator.
