BATTERY SIZE I WOULD LIKE TO KNOW WHAT SIZE BATTERY THIS WATCH USES

Question edited for clarity FULL 'make model (what is is).
Question moved from Cars and Trucks, which also doesn't help identification of the mk 5603 or mk5603!

Best advice right here. Also "the same as the one that is in it".

it uses SR920 size of battry. i hope i had been helped you.

there are small screws at the back, take it off using small tools and lift the back. it uses SR521 size of battery. i hop this will helped you.

it uses sr920 size of battery and you have to have caseback opener to removed the cover.

691 and 901 just different size battery as 691 uses cr-2320 and 901 uses cr-1620 size.

the size cell that goes in this watch is a 395...good luck :)

I have a Hugo Max HM13 watch with 10 diamonds and it uses a silver oxide battery No. AG4, or 377 or LR626 or SR626SW or 177. These are different numbers for the same 1.55v battery.
