had mine repaired by a really good jeweler in wootten bassett , they said it was poor quality but repaired it and been fine since, just sent him another for the astura and an ODA belna clock for repair, will let you know how i get on , my dad did copy faces to convert smiths 8 day clocks to metron lookalikes , have one in his old car as not had time to fit the metron, i can't remember but i think he may have put it in the news letter at somepoint
