It seems to me that these are unappreciated and undervalued watches. They're solidly built, come in a range of interesting dials, and have quite good movements in them. Typically, we're talking Val. 7730/7733, though not a few sport the excellent Lemania 872.

This one is quite Siffert-like (minus the bezel).

 

Mine says hi.

 

This Navigator is powered by an in-house Tissot Caliber 28.5N-21T automatic

 

I'd agree with Tissot in general being undervalued; I think these Navigators (I've got a V7734 Seastar like @nzshadow) are just *killer* watches, and I think lots of Tissot's best stuff's held back by size (their early time-onlys wear smaller than equivalent Seamasters) or shape (I don't see a ton of enthusiasm for tonneau-shaped 1970s chronographs, at least at the moment).

 

I love the Tissot Seastar chronos with Lemania movements.

 

I believe these are very underrated models too. The T12 is a classic with the 872 at a fraction of the price of a 1970 Speedy. I know style is not to all tastes but it’s certainly distinctive! Here’s one of mine.

 

These have so many fun variations. I keep eyeing the ones with a central minutes counter - I really enjoy that arrangement.

 

Thanks for bringing this model up... so many watches I’ve yet to look at.. and being smaller size works really well for me!

 

Sorry not only Navigator but only Lemania movements.

 

My NOS Tissot Navigator with Lemania 1341 says hello:

 

This is absolutely beautiful. What is the approximate year of production? Is the box the actual one that it was sold with. NOS is a much overused term but this set truly looks new.

 

I cannot answer all your questions.
I bought this watch a few weeks ago from a collector.
He told me, that he bought it end of 80s/beginning of 90s on a watch fair.
He bought this watch with the genuine leather, clasp and with this box.
If I am honest, I cannot tell, if all the parts belongs to this model (but I think so).
He bought it as NOS and never used it...

 

A beautiful set, indeed! Every bit as nice as the Seamaster 176.007.

 

Love them!! So many variations with different movement options but styling for every taste too!!

 

No longer have this one unfortunately but it was a great watch. Given condition, it was at the more expensive end of the Navigators, but I've seen far worse commanding high prices. Most I see have very worn or damaged outer bezels, and there is no way of replacing them as you cannot get parts. When I say high prices, this is still an affordable watch compared to most vintage chronographs, and I like that about it. You won't find many in this condition, though.

 

I will say that it's around 1974 and box is from the same ages.

 

But as started by Vitezi, Navigator is not only chrono..but also diving watches

 

Thanks for posting the magazine ad. I have a soft spot for the early 70's designs.

 

Really like the versions with central minute chrono hands, very legible, and the Yachting versions add some color as well.
