Wittnauer Professional 3507/247T Chronograph c.1970
We don’t like to throw the word “rare” around because it, ironically, gets used all too often these days. We prefer simply saying something like…”Good luck finding another one!”
Wittnauer Professional chronographs are extremely popular these days, but you’re generally seeing only seeing a handful of models commonly popping up. Enter the ref. 3507/247T.
If you’ve ever seen this model, it’s likely been a “surfboard” dial variant, but this blaze orange dial variant is all but undocumented. With massively raised black + lume indices, broad silver baton hands, classically sunken subdials, and a dial that you can see from a mile away…this one stands out a little — to say the least.
Powered by an ever-reliable Valjoux chronograph motor, this is either a timepiece fit for the daring enthusiast or the ultimate Wittnauer collector. We’ll let you decide.

[All vintage watches are expected to function as described. However, due to age and generally unknown service history (unless otherwise stated), these watches may not keep time as accurately as new or quartz (battery) watches. This is completely normal and does not indicate that there is a major problem. Like your automobile, all mechanical watches will likely need to be serviced at some point in time. Please keep this in mind, as there is no guarantee regarding when these vintage watches may need standard maintenance. Every watch sold by Buying On Time is done so with the expectation that it is not currently in need of service or repair, unless noted. We guarantee that all watches sold are accurately described and in the stated condition when they leave our hands.]
