Tiret can be a little, err, hit and miss with their models.
Thankfully, this one isn’t too over the top.
The Power Reserve Floating Diamonds features a 42 hour reserve ETA 2897 automatic movement.
This features a visible Tiret New York engraving; additional train wheel bridge with Tiret New York engraving on side and an oscillating surface smoothed weight.
Not much else of use in the fluffy press release I’m afraid :-)
