Hello everyone. Although I don't own a Zenith yet I am a huge fan of the brand and I've been saving money for some time now hoping to buy my grail watch, discontinued model of Chronomaster, triple date, moonphase chronograph. Financially, I am not 100% there yet but recently I have started to browse some sites, getting to know the prices and the market better. Anyway, recently, I've found one watch that got me interested but at least two things got me a bit concerned. Since I am not an expert on these watches I wanted to share my concerns with you guys and ask for your opinions.
First thing I noticed is that a watch has COSC certificate... I think. On some photographs I noticed a document titled 'Controle officiel Suisse de chronometres' but unlike COSC certificates that I've seen online this document doesn't show measurements that one would expect - results of timekeeping in different positions but general dimensions, weight etc. Is this maybe just the first page of COSC and measurements are shown somewhere else? Also, in another excellent thread on this forum I have read that Zenith stopped issuing COSC certificates for Chronomasters somewhere around 2001 - 2002. Judging by the temporary warranty card this watch was sold in 2006. Although it is quite possible that the watch was manufactured before 2002 I believe it's highly improbable that it was sitting in store for at least 4 years. Also, I am not 100% certain but I think that I have read somewhere that around that time (2001-2002) Zenith introduced black dials to this models, possibly 'guilloche' finish... While we are at it, since 'guilloche' or better yet 'textured' dial is my favorite dial finish for this model, are the any watches of this model with this type of the dial produced before 2002 and with 410 movement (instead of 410z)? Seller didn't post a detailed picture of the back but I suspect that the rotor has... hatch engraving without serial number on it so I suspect that the watch was produced after 2002.
Another thing that I noticed are two distinctive handwritings and two pens used for filling the temporary warranty card. Again, I am not 100% sure but aren't those cards filled at the moment of purchase? If so, wouldn't it be logical that the one person, with the same pen, fills this card? I asked the seller for additional pictures and explanations but I didn't get any. To summarize:
- Is it possible that the Chronomaster produced after 2002 has a COSC certificate
- When was textured dial introduced to this model
- Should I be concerned about two handwritings on a warranty card
For academic purposes, I'd really appreciate if you'd share any thoughts about these matters. Thanks!
