Second watch from Neco Clock and probably my last for a while. The Nautilus 5711/1A looks right, the end link fit is a step up from the earlier TWF batch I had.
Honestly you will not notice it once it is on.
Any chance of a lume shot?
That is a clean example. Which batch?
I have the same one from THB and it has been solid.
