Hi, Catherine,
Yes, at this moment, 37 mm watches ware even considered too big!
Using a 42 mm was a brave decision for U.G, JLC and Longines, but I'm preety sure I forgot some, here.
Nowadays, 42 mm are more normal than 37 mm for Diving watches, and seem even small compared to the Tuna Fish Panerai Cans.
Still, I love the IWC, as I'm hunting it for several long years, now, and I also love the 42 mm super compressor cases for their charm.
Happily, we're not all in love with the same lady!
Best,
Nicolas
