ETA Unitas Caliber 6497 VS. 6498 Watch Movement

Postby koimaster » April 9th 2018, 9:56am

The major difference between the Unitas/ETA caliber 6497 and caliber 6498 is the location of the small seconds subdial.

Sub seconds placement, that’s all folks!

Imagine these watches as the were intended: as pocket watches. The 6497 would be in a Lépine (open face) pocket watch with the crown up. The 6498 would be the movement in a hunter style pocket watch with the crown to the right. Both would have the seconds at the 6:00 mark, but changing the crown position by 90 degrees would change the seconds position as well. When used on a standard wristwatch, this gives two options for the seconds placement when designing the dial.

Which one is more popular?

Do you know of more pilot watches with the small seconds at 6:00 or 9:00? It seems that there are more 6:00 subdials out there, making the 6498 more popular. However, with that said, you may find that more listing mix these movements up and list most watches as having the 6497 without actually knowing the difference. Hopefully this post will change that!

What is the difference between calibers with “-1” or “-2” at the end?
