Just been given this lovely Nisus by a colleague. It hasnt been wound in over 30 years but fired up straight away and is keeping good time :D The seconds hand was floating around under the crystal, so that was my first job. It is a front loader so it was easy. The case is gold plated and the strap is apparently the original one. I usually mess around with huge Pam homages and it looks ridiculous on my 8.5" wrists but this little gem has got me hooked!
