This is marked -68 in the back. If it does not have 68 in the back then I do not consider it a transitional.
These are worth more than the much more common painted logo 145.022-69. They are very rare, and when one comes on auction there are many buyers. Prices are higher, but there are so few traded that pricing them is not easy to be precise. If you look with $8000 (January 2020) in mind, you could go up or down from there, but it is essential it carries all the Transitional elements.
As always the value depends on the condition, but the DO90 bezel it carries is becoming so valuable, that valuing the watch involves valuing the bezel. Recent prices for top, flawless bezels have reached $5000, which can be more than half the value suggested for this reference. Do not forget very few bezels are that much.
These early calibre 861’s carried a dial with a similar design to the 145.012. These dials have an applied metal Omega logo, and long hour indices. The dials look the same as the one fitted to the 145.012, but they have different size feet, although in the same position. If it does not have this dial, it cannot be a “Transitional.”
This one has the square end Chrono hand.
It has a lovely dial and I would be considered very good.
The word “Transitional” here is used to describe this specific reference. It is the transition between the 145.012 and the painted logo dial, 145.022-69.
Confusingly the word is often used as an adjective elsewhere – for example when discussing the straight engraving case back, and even when discussing the 105.002 – as a “transition” between the 2998-62 and the 105.003. When used here as a noun, the term Transitional describes a 145.022-68 with the following attributes:
I have see a Transitionals with -69 stamped in the back. I now believe that if a watch has the rest of the characteristics, including the serial, then if it has a -69 back it has the incorrect back.
All Transitional should have a DO90 bezel.
I have just bought a new one, read about it here
Here is a very nice transitional, with a square end chrono. Note the long indices on the hour markers. This also has a case back marked in the back -68
