A lovely looking watch which is new and unused in its original packaging with paperwork. The case measures approx 38mm although given the material there is some variability, the manufacturer says to allow plus or minus 2mm. Please compare with another you have access to to check sizing. There is a small plastic clip alongside the crown as shown in close up. The watch will only begin to tick when you slide this out, spin the crown to the correct time and then gently click the crown into place alongside the case. The box will likely be bubblewrapped and posted in a plastic mailing bag. Just let me know when ordering if you require additional or alternative packaging.
