Ingersoll Bison 18 PVD Open Escapement Dial

Automatic watch with an exposed balance wheel at 6:00.


Ingersoll watches are produced in limited editions and when they decide to stop making a model, it’s gone forever. Also, Ingersoll is currently without distribution in the United States, making it harder for Authorized Dealers like KeepTheTime to get product. Luckily we still have one of the very popular Bison No. 18 watches in stock.

Desirable Model

This is one of the original and most popular Ingersoll watches ever produced. It has a solid case design with a beautiful finish, a dial layout that makes sense, featuring a big date at 12 and a cool open skeletonized balance wheel at 6. The rivets on the leather strap and big onion crown make this a classic pilot style watch with a modern twist. Get it before it’s gone forever!

Why Ktt Specs

Watch You See Is Watch You Get

Since the company was founded, KeepTheTime has been well-known for our watch photography. No stock photos! After the logging and inspection process, our in-house photographer gets up close and personal with each watch. After the photoshoot, the research begins, verifying the detailed specs by hand. That's why you will know exactly what you are getting when buy from us.

Second To None Packing + Shipping

Actual customer comment: KeepTheTime is the Brinks Truck of shipping watches. We take packing orders very seriously, from the use of pet-friendly biodegradable peanuts to absurd amounts of packing tape, you can rest assured that your new-to-you watch will arrive safely. Some sellers ship within 1-2 weeks because they take your money first and source the watch second. KeepTheTime watches are in stock and ready to ship, so we can get your order on its way within hours not days.
