Normally I-Rings for around 1mm Crystals are either **.2 or **.7 to match with **.5 & **.0 crystals. i.e. a 32.2mm I-Ring would be a 31.5mm Crystal. Based on your measurements I'd have thought the 31.5mm would be correct. Where did you get it and did you measure it? Edit Just looking at your photos. Was it a double dome 1.1mm originally as the I-Ring looks very deep for that size? -
First major fail. Finally got in my replacement crystal. Ordered 31.5mm x 1.1mm double domed mineral glass. But it didnt snap in. Tried adjusting but I was able to pop it out by hand easily. Tried again and again until I shattered the crystal. With the gasket in the case the inner diameter is 31.5mm, with out the gasket the case inner diameter measures 32mm. What size should I go with? -

Hello everyone, I recently encountered an issue while working on my Seiko 4006 movement and could really use some advice from those with experience in watchmaking. I purchased a new mainspring from Cousins GR2378X and attempted to install it straight into the barrel without success. Subsequently, I used my Bergeon NO7 Left hand winder and managed to successfully place the mainspring into the barrel. As the original barrel arbor was missing, I had already ordered a replacement from Cousins (part number 213805). However, I’m now facing a problem: when I insert the new arbor into the mainspring, I can’t get the barrel lid to close—it simply won’t fit. I've taken several photos to illustrate the issue, which I will share for better clarity. I know I must be doing something wrong, but I’m not sure where. I’d really appreciate it if someone with experience could shed some light on what might be going wrong. Thanks in advance for your help! Best regards, TT -
Yes but not for a while as my eyesight isn't good enough at the moment. The 2614.2H is about as small as I can go.

I would have a look for PCTM watch timing software. We have an expert on this software as a member @praezis. Oh, there is a free version as well as pro level. No affiliation etc. Tom
