Hello OMega Forums, I'm wondering if anyone can confirm if the crystals for most 321 references are different from the 861 145.022 reference. More specifcally when it comes to the Omega Service crystals is Part # 063PZ5078 (for CKs and 105.003) a different size than the crystal Part # 063PW5139 for the 145.022.

Can anyone here shed any light on the idea that the '78 145.022 batch's cases were made by a still unknown manufacturer? As far as I know that esoteric symbol on the caseback interior was only on the '78 batch. According to "Craft and Tailored" the manufacturer remains a mystery……. can the forums solve it? Here's mine ( i use a false bezel DO90 in order to keep the original bezel (DN90) stored away for safe keeping- for those that might notice its the wrong bezel).

Best and thanks to…
