Hi everyone, new here and new to watches really. Thinking about buying a Tag Heuer for my first. Can someone tell me if CAZ1110.BA0877 and CAZ1010.BA0842 are the same watch? They look like it but I'm just wondering why they have different model numbers and what this represents? Sorry I can't post links, one is from Beaver Brooks and the other is from Goldsmiths. Thanks!
