This is a restored, working "Y749-5020" released by SEIKO's ALBA in 1980. I acquired this as dead stock, but the inside had suffered damage due to battery leakage, so I transplanted an entire working module of the same type. The module used for the replacement is also in very clean condition, and all functions and operations are currently good. However, this item has been completely disassembled during the restoration process, so please refrain from purchasing if you are hesitant about restored/repaired items. The case is not a plastic case, but a metal case with a matte black finish. It is very clean as it is dead stock, but there are some scratches and slight peeling due to aging, so please check the photos for details. The gasket on the back cover was somewhat hardened, but it was not broken, so it has been installed as is. I don't know how much water resistance it has in its current state, but considering its age, it's best to avoid water. The battery has been replaced. Separately from the main body, I will also include a working module of the same type, although it is not in good condition. The circuit board is still functional, so please use it as a spare in case of failure. This is a very rare dead stock Y749-5020. If you were looking for one, please consider it. ✳︎Before purchasing✳︎ This is a precision instrument that has been in use for many years since its release. There is a possibility that it may suddenly stop working during use, so please purchase only if you understand that it is "junk that is usable at the present time." We do not accept refunds or returns for any reason after shipping. We also refuse purchases from those who are looking for a new-like condition, those who are sensitive, and those who are hesitant about restored/repaired items. Please feel free to ask if you have any questions. Thank you. #Y749 #Deadstock #Outofprint #ALBA #Alba #Seiko #70s #80s #Vintage #Digital #Rare #Rare #SEIKO #vintage #digital #80’s #70’s
