First post, confusion with case numbers

[Cox]

Hello, I recently acquired an ENICAR Ocean Pearl. The movement is a 1147c. The outer part of the case back is marked: 147-01-15. The inner part of the case back is marked: 2335.The case is gold-plated but no longer in good condition. I'd like to replace it with a stainless steel case. Unfortunately, I'm quite confused about the numbers and their meaning.I think 147 refers to the movement.I'm not sure what 01 means.15 could refer to the material, i.e., gold.I found a very nice stainless steel case, marked 147-01-09 and 2334. Could 2334 refer to the case shape? It's rounder than mine. Would 09 then be the code for stainless steel...? Would it fit?

I also found this case (which I don't want to buy). It's made of steel, and I think that's what the number 18 stands for. However, the shape isn't the same as my case, nor is it the same as the stainless steel case.
Like I said – I'm confused.

The reference number identifies a specific watch model. Different reference numbers may indicate different bezels or different finishes. At least in the case of Enicar, the reference number does not indicate the case material used. As you can see from the catalog image, your reference number 147 01 15 was used for both the gold-plated and the stainless steel models.

Thanks for this information.

How can I find out if a case is compatible with my watch movement before I buy the case? Is the caliber number, in my case 147, enough?
