ETA caliber 956.102 is a small diameter, ladies-size quartz watch movement with 7 jewels. The 956.102 is a 3-hander with no date – it is a “true no-date” with only one crown position for setting the time.

Movados Using 956.102:

The image above is from a ladies Movado Concerto watch with only 2 hands (hours/minutes). In line with this, the movement itself is signed “Movado 2 Hands”. Technically the 956.102 is a 3-hander with a seconds hand. There is a calibre in the 956.XXX family of small quartz movements which is a 2-hander from the factory: ETA cal. 956.032.

Movado is known for watches without a seconds hand, but the reason for choosing a 3-hander movement for a 2-hander watch could be that the 956.102 is more readily available from ETA; the price could be lower in bulk; or Movado could have other models (or a shared purchase order with another brand) using the seconds hand, so perhaps they order one movement to keep costs down and simply don’t install a seconds hand on pieces with a 2-hand design.

Also bear in mind that if you found this page by searching for the movement in your Movado watch, the EOL (battery end of life or low battery indicator) will not apply, as the EOL is conveyed via a skipping seconds hand.

Speaking of batteries, ETA calls for a battery cell 364, but the Movado caseback calls for 377.

The 364 and 377 batteries have the same diameter, but the 377 is a thicker battery (it also stores more energy and therefore lasts longer).

Not all watches can accommodate the taller 377, and some watches may have a battery cell spacer that looks like this.
