Before purchasing please note the PROS & CONS of buying prototypes.

CONS

• Prototypes do not go through the same level of Quality Control the Full Production Watches go through - so they may or may not have imperfections that show up with a macro camera lens like Gary from I Like Watches pointed out in his Review of the M3.

PROS

• It’s kind of special ‘cause there’s only 5 made in the whole wide world.
