I think they are quite exacting on marks/damage to crowns.
Only if the ‘chips’ on crystal is likely to affect waterproofness will they insist on renewal from what I understand.
A Seadweller 16600 service is £600, which seems unusual considering the helium escape valve that model has.
I got a call from dealer yesterday, saying that crystal renewal was ‘optional’ but since the marks on edge of crystal were so slight - I opted to leave original.
