Metalem versus Comblemine! I've tried and partially failed to find two dials with similar guilloche patterns. Nonetheless, I ask that you not judge the watch or the dial design (It's hard, I know, but try to put aside your feelings about either watch). Instead, I ask your sense of the quality of the work done by these two dial companies. I'd say they both do great work, but what do you say?
Metalem made this dial to Czapek’s specifications

Another by Metalem for Czapek. It's a sort of variation of grain d'orge / barleycorn pattern with two foci, perhaps?
Comblemine made this dial for Armin Strom a classic barleycorn pattern
Another by Comblemine in a sunburst pattern for Armin Strom
