Advice on a Zenith 18K gold cushion faced watch (circa 1919).
I've been left a Zenith Cushion Face watch Circa 1919. Its in great condition with a blemish free face and the original glass and case (the case is 18k gold). The only flaw is a cheap strap and a small pinhole in the gold case. I took it to a horologist (?) in Melbourne Australia who advised me that the movement was in good condition as was the mainspring and it only really need a clean, polished case and the pinhole repaired (via laser). I will try and post some pictures if I can figure out how to pot them.
What kind of value would there be on such a watch? The horologist has quoted me $750 AUD ($740 american) and I'm wondering if its worth getting it fixed and possibly selling it as there is no real sentimental value in it.
