An alternative or archaic term for someone who makes, designs, or works with dials and dial-related devices.
From dial + -ister (a variant agent suffix, less common than -ist). This appears to be a less frequently used variant of 'dialist' with similar meaning but different suffix formation.
This is the kind of obsolete occupational title that shows up in medieval records—crafts became so specialized that different regions called dial-makers by slightly different names, just like we have variations today.
