An unusual looking 454 Calibre

I came across this unusual looking 454/3 calibre and wondered if anybody had seen anything else like it?

An unusual looking 454 Calibre

It appears to have gold bridges and a Freesprung Gyromax balance which I did not think were used in the 454 calibre.  It also looks like some of the screws are missing from the movement.

Any ideas?

a cal 453, 458 or 466 as they look similar and hard to say from the small photo. However I have see these calibers with the gold plated bridges.


However balance is not free sprung as you can make out the index regulator

That is a cal 454 from the late 30's early 40's. Before it was required to note the number of jewels and adjustments. It was from a "teardrop" case. That crown is worth it's weight in anti-matter!

I agree with LSmith

I've seen gold plated versions of cal 454, both with and without a swan's neck micro-regulator from the early 1940s.

I almost bought one once, with a steel, teardrop, case.  I even made payment on it, but then found out the serial numbers didn't match.  Luckily the seller was willing to negate the sale and return my payment.
