    Vostok НВЧ-30 (NVCh-30) History & Research Guide

    Hello All,

    For all of you interested in the Vostok NVCh-30 military issue divers watch, there is now a new collectors guide available. This is a live document so will continue to be updated.

    https://docs.google.com/document/d/1...it?usp=sharing

    This document is also available to view on fellow forum member Dashiell Stanford's web site.

    Thanks to Dashiell for his assistance, I hope the guide continues to be of assistance to all fellow collectors.

    Cheers...

    Re: Vostok НВЧ-30 (NVCh-30) History & Research Guide

    Thanks very much Matt for the link of this much interesting article extremely well documented .

    This part caught my attention «. The last batch of the НВЧ-30 (Models 119-630) used modified civilian cases in which the 18mm lug width had been machined out to 22mm to meet the military contract requirements. Many NOS examples can been seen with traces of this extra machining. Others show off-centred lug cutouts.

    Does that implies that it is possible to find authentic NVCH with 119 cases that have the little flatter part in the middle of the arch on the back of the case ? I happen to have such a case displaying concentric traces on machining on the 22mm lugs space .

    Of course I found both types, flatten or perfectly smooth, of «.arches.» on some of my civilian 18mm lugs Amphibians as documented in Phil’s work

    Until now, based on the above, I had deemed the case on my NVCh as non original, so thanks vm Matt for taking to time to shed any light on the matter

    This is certainly a possibility, although authenticity is always judged on the complete watch. If in doubt post up some pictures.

    Cheers...

    Phil's work is to be commended, but it is an observation and not a rule. There are many exceptions.18mm cases that have exactly the same characteristics as the 22mm 300m cases.

    Your 22mm lug case looks perfectly acceptable.

    Cheers...

    Excellent write up, Nice to have almost all available information in one handy place. Any chance we could see some more info on the supposedly genuine straps found for the wire lug 300m? You know what's odd, so far i have been unable to find a picture or mention of the tonneau model in the diving books. Both the zlatoust and swing lugs 300m can be found but no tonneau.

    I could have helped out on the 3rd generation chapter, after all i did quite extensive research on the subject
