Super Rep

The community's informal top quality tier — factories producing the closest dimensional and finishing match to the genuine reference, often using the same case/bezel/bracelet supply chain logic as high-end aftermarket parts makers. “Super Rep” is a relative, moving target: today's Super Rep tier is yesterday's unreachable benchmark, which is part of why the NWBIG sentiment exists at all.
