They do have that design in the 3-1/2", and they have a different design in the 2".
Can the crystal be removed and any image you desire be put in? I ask because I noticed they have the insert that photos can be placed inside.
I found some 2-3/4" here...
2 3/4" Clock Inserts
The place you linked to is associated with Wildwood Designs which is where I get most of the inserts and that is why they carry close to the same things. I have the 2 3/4". That is the largest size I use. Those inserts can be reworked because the bezel is plastic and the trim ring screws off. It takes some work but I have done it before.
The 2" is a glass bezel with a solid brass plated ring and no there is no way to rework these without taking the guts out. They are a sealed unit. Way too much work for that. The place I use to buy them had some with a white background but stopped carrying them also. I believe when the 1 7/16 get sold out that will be the end of them unless Tawain starts producing again.
I have gone through this before with other inserts and eventually all vendors sell off the remaining stock. Being I was away from doing this work for almost 3 years I lost touch or lost my pulse on what was happening and this caught me by surprise. If I had known it I would have bought out many vendors stock. I use these inserts in many of my clocks.
Thanks for the link and the idea. I am sure I will work something out. I am hoping if enough vendors try to reorder them that the supplier will put back in production. Supply and demand as they say.
