It looks like a Watchco put together example, its a luminova service dial that lacks the word Seamaster, and the orange hands are meant to be on a grey dial version, not a white dial.
Indeed, also I think the only bracelet options available were the 1170 that you have which fits flush, or the flared non-flush one I have on mine, I don't think mesh would have been ever offered on it (even though it does look good).
And indeed it does . But getting back to the nerdy stuff: Ash, I think mesh is a popular option because so few of the correct 1170 bracelets are around. AFAIK mesh was never original to these.
Mesh looks good on everything One day I need to find some 20mm lug Patek in white gold, mesh the bitch up
My wife has just got her watch back from Paul in England (thanks to both of you!) Great job and service. Recommended!
