Can not get that link to open. Have another link or just place the name of the company and i will google. Thanks 1-7/16" inserts are not all the same. Sloans still sell Seiko inserts and they are some of the better ones. The ones I shown are not that size, they are a bit larger and I usually buy in 2 different sizes. I like to use 2" inserts also.
Just a note on the 2-3/4" inserts and larger made in China. and also ones made in the USA. I have seen this many many times, the clocks are basically kits that are interchanged with different faces. You can many times unscrew the plastic bezel. I say this because I have had clocks come to me where the hands are not seated just right. They may touch the glass or bent too much and scrape the facing or too loose and skip time. The motors work fine but it is the hands that either stop it or fall off. Can easily be fixed by taking the top off. Have seen this on both USA and China models. That is why I suggest a trial period before installing.
Here is the old thread that has some info in it
