Can I use another cell instead of CR2032?
Verdicts follow our swap rules from the datasheet size, voltage and cell type.
No: CR2025 is 0.7 mm thinner than CR2032.
Same 20 mm diameter, but CR2025 is 2.5 mm against 3.2 mm: the contact spring may not reach it.
CR2025: 20 mm5 × 2.5 mm5, 3 V5

Questions
What is the CR2032 battery equivalent?
ECR2032, DL2032, SB-T51 name the same 20 × 3.2 mm lithium coin cell as CR2032. Any maker's cell under one of these codes fits.
Is CR2025 the same as CR2032?
No. CR2025 is 0.7 mm thinner than CR2032. Same 20 mm diameter, but CR2025 is 2.5 mm against 3.2 mm: the contact spring may not reach it.
What watches use the CR2032 battery?
In our base: 30 Seiko calibres (B010, DH33, S031, S032…); 12 Casio models. The full lists are on this page, with the brand tables they come from.
How long does a CR2032 battery last in a watch?
Seiko's battery chart gives 2 to 5 years for its 30 calibres on this cell, 3 years most often. Life depends on the calibre's current draw, not on the cell alone.
