Sunon SL28D is a three-hand date quartz movement in the Standard Series. The official product page specifies 4.15 mm movement height. The secondary reference reports 23.7 mm diameter and a 6 mm total height, which must not replace the movement-body height. It uses an SR626SW battery and contains no jewels. SL28DD is a distinct day/date version; the seller suffix SL28D-3 is not a confirmed separate variant.
