Can I use another cell instead of CR2016?
Verdicts follow our swap rules from the datasheet size, voltage and cell type.
No: CR2012 is 0.4 mm thinner than CR2016.
Same 20 mm diameter, but CR2012 is 1.2 mm against 1.6 mm: the contact spring may not reach it.
CR2012: 20 mm5 × 1.2 mm5, 3 V5
Draw both cells in the swap checkerNo: CR2025 is 0.9 mm taller than CR2016.
Same 20 mm diameter, but CR2025 stands 2.5 mm against 1.6 mm: the case back presses on it or does not close.
CR2025: 20 mm6 × 2.5 mm6, 3 V6

Questions
What is the CR2016 battery equivalent?
ECR2016, DL2016, 280-206, SB-T11 name the same 20 × 1.6 mm lithium coin cell as CR2016. Any maker's cell under one of these codes fits.
Is CR2012 the same as CR2016?
No. CR2012 is 0.4 mm thinner than CR2016. Same 20 mm diameter, but CR2012 is 1.2 mm against 1.6 mm: the contact spring may not reach it.
What watches use the CR2016 battery?
In our base: 77 Seiko calibres (7C21A, 7K52, 9M21, A708…); 1 Citizen model; 360 Casio models. The full lists are on this page, with the brand tables they come from.
How long does a CR2016 battery last in a watch?
Seiko's battery chart gives 1.5 to 10 years for its 77 calibres on this cell, 3 years most often. Life depends on the calibre's current draw, not on the cell alone.
