Hi. Thanks for your question. The diameter of the SBBN007 crystal is 32.5mm. The part code is 325W16GA00 or 325W26HB0A, which is also used on SBBN031 (and other tunas). According to this forum thread, it's possible to put the flat crystal from SBBN045 on an SBBN031: www.watchuseek.com/threads/sbbn045-tuna-and-backwards-compatibility.5249479/ Therefore it should be possible to fit the crystal on an SBBN007 as well. However, I'm afraid I don't know the part number of an SBBN045 crystal or how much it costs - sorry.
