Cell types in this size
3 cell types share the 11.6 × 3.05 mm size.
SR1130SW
Low drain (SW): for plain analog watches · Silver Oxide3
14 codes in our sources name this cell type.
SR1130W
High drain (W): for watches with lights, alarms or chronographs · Silver Oxide5
11 codes in our sources name this cell type.
SR1130
Primary cell
0 codes in our sources name this cell type.
LR1130
Alkaline cell of the same size: the IEC digits are the size, the L is the chemistry. LR1130 lands on this page by that rule; our sources hold no alkaline datasheet for it, so no figures are shown.

Can I use another cell instead of 390?
Verdicts follow our swap rules from the datasheet size, voltage and cell type.
Use instead of SR1130SW
SR1130W
Fits, with a catchFits: SR1130W is the high-drain version of the same size.
SR1130W and SR1130SW are both 11.6 mm × 3.05 mm, 1.55 V silver oxide. SR1130W is made for bursts of current (lights, alarms); in a plain watch it works but may not last as long as SR1130SW.

SR1130
YesYes: SR1130 is the same size and chemistry as SR1130SW.
Both are 11.6 mm × 3.05 mm silver oxide, 1.55 V.
Draw both cells in the swap checkerUse instead of SR1130SW
LR1130
Fits, with a catchFits, but LR1130 is alkaline and runs shorter.
Same 11.6 mm × 3.05 mm size. LR1130 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR1130SW.
Draw both cells in the swap checkerNo: SR1120SW is 1 mm thinner than SR1130SW.
Same 11.6 mm diameter, but SR1120SW is 2.05 mm against 3.05 mm: the contact spring may not reach it.
SR1120SW: 11.6 mm6 × 2.05 mm6, 1.55 V6
Draw both cells in the swap checkerNo: SR43SW is 1.15 mm taller than SR1130SW.
Same 11.6 mm diameter, but SR43SW stands 4.2 mm against 3.05 mm: the case back presses on it or does not close.
SR43SW: 11.6 mm6 × 4.2 mm6, 1.55 V6

Questions
What is the 390 battery equivalent?
SR1130SW, SR1130W, SR1130, V390, B-SR54L, 603, 280-24, D390, 9924, 080-D15 and 12 more codes name the same 11.6 × 3.05 mm silver oxide cell as 390. Any maker's cell under one of these codes fits; match the drain type (SW or W) when the watch maker names one.
Is 381 the same as 390?
No. SR1120SW is 1 mm thinner than SR1130SW. Same 11.6 mm diameter, but SR1120SW is 2.05 mm against 3.05 mm: the contact spring may not reach it.
Can I use 389 instead of 390?
Yes, it fits: 389 is SR1130W, the high-drain cell of the same size. SR1130W and SR1130SW are both 11.6 mm × 3.05 mm, 1.55 V silver oxide. SR1130W is made for bursts of current (lights, alarms); in a plain watch it works but may not last as long as SR1130SW.
Is LR1130 the same as SR1130SW?
No: LR1130 is an alkaline cell of the same size, SR1130SW is silver oxide. Fits, but LR1130 is alkaline and runs shorter. Same 11.6 mm × 3.05 mm size. LR1130 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR1130SW.
What watches use the 390 battery?
In our base: 61 Seiko calibres (7121, 7122, 7123, 7126…). The full lists are on this page, with the brand tables they come from.
How long does a 390 battery last in a watch?
Seiko's battery chart gives 1 to 5 years for its 61 calibres on this cell, 2 years most often. Life depends on the calibre's current draw, not on the cell alone.
