There's generally a lot of interest here in vintage chronographs with a racing pedigree, eg. the Siffert Autavia, the Bellof Montreal, the Jim Clark Enicar.
Here's one, my latest acquisition, from the other side of the world that is perhaps not so well known, the titanium Walter Wolf Citizen 8110 Chronograph.

This particular watch dates to Nov 1983 by serial number (gotta love these vintage Seikos and Citizens - their serial number allows one to date the watch to the month and year of production!), and is 39mm across.
Appearance wise, it's a little busy, what with cardinal directions on the countdown MH bezel, and the dial containing the prominent Walter Wolf logo, day (in Kanji)/date indicator, as well as the 2 subdials, all surrounded by the inner Tachymeter bezel.
But everything's arranged nice and neatly, and to me, overall, it's a pretty package!
The movement is the well regarded Citizen 8110A that ticks all the right boxes - column wheel, vertical clutch, flyback, 28800bph chronograph.

Oh, and one point of criticism - the crown is way way too small for effective winding!!!

I had to do some googling to find out about Walter Wolf Racing, but it does seem to have fairly eventful, though short-lived existence.
Their debut year 1977 was most definitely their best year, with their driver Jody Scheckter winning 3 races (Argentina - a win in their debut race!, Monaco and Canada) and achieving 6 other podium finishes to eventually finish 2nd behind Nikki Lauda in the world championship, with the team achieving 4th place in the constructors championship!

Well, enough of all that, here's a couple more photos!
Anyways, I think it's a big shame that this little Citizen flies just under the radar, just slightly unknown and unappreciated.
To me it's a gorgeous watch, which should have it's deserved, rightful place amongst its much more well-known Heuer and Enicar brethren!
