Seiko case-codes are ALWAYS a set of two letter/number combinations seperated by a dash (-). For example: 1100-4840, 6N42-00F0, W853-4000. Please note that the codes never contain the letter O. This is always a zero.

Please do not type any other texts than case-code or product code in the search field. If you wish to search for a Seiko sub-brand (e.g. Astron, Presage), please use the search filters.

To make sure that your new Seiko watch band fits your current Seiko watch, check the model number on the back case of your watch and search the model number using the search box above.
