[Help] Seiko Calculator Watch

[Alex]

Hello guys,

I have bought recently a Seiko Calculator Watch (I don't have it with me right now, so I can't tell the model reference).
Aparently it works good but I need get a back cover to secure the battery.Anyone know where I can get one?

there very hard to come by. also a common
missing part of these models
best bet is to buy a beater and salvage the part

Thank you :)
