N1 Factory Omega Speedmaster Professional Moonwatch QC Test

N1 Factory Omega Speedmaster Professional Moonwatch QC Test

The N1 Factory Omega Speedmaster Professional Moonwatch is one of the more noteworthy manual-wind Speedmaster replicas currently available. During our pre-shipping inspection, this watch demonstrated stable movement performance, accurate case dimensions, and a weight that closely reflects expectations for this configuration.

Powered by a manually wound Cal.3861 clone movement, it delivers a traditional Moonwatch winding experience while maintaining reliable timekeeping during testing. Compared with many alternatives, N1 Factory offers competitive case proportions that closely follow the original design, making it an option worth considering for collectors who value accurate dimensions.

As with all mechanical watches, slight differences in daily rate and weight may occur between individual pieces due to assembly tolerances and production batches.

Movement Performance

The manually wound Cal.3861 clone performed consistently during QC testing, recording a daily rate of -8 seconds per day, an amplitude of 284°, and a 0.0 ms beat error.

The healthy amplitude and zero beat error indicate stable operation at the time of inspection. As with any mechanical movement, real-world performance may vary depending on winding habits, wearing conditions, temperature, and positional differences.

Dimensions & Wearing Experience

One of the strengths of the N1 Factory Speedmaster Professional Moonwatch is its overall proportions.

The 42 mm case diameter and 13.3 mm thickness closely reproduce the proportions of the original Moonwatch, resulting in a balanced wrist presence. Combined with an approximate weight of 136 g, the watch offers a comfortable wearing experience suitable for daily use.

Among currently available factories, N1 Factory is particularly competitive in maintaining accurate case dimensions, making it a version worth paying attention to.

Sapphire Crystal

The watch is fitted with front and rear sapphire crystals, providing excellent transparency while allowing a clear view of the manually wound Cal.3861 clone movement through the exhibition caseback.

Overall QC Assessment

Based on this individual QC inspection, the N1 Factory Omega Speedmaster Professional Moonwatch demonstrated stable movement performance, accurate dimensions, and solid overall build quality.

For enthusiasts seeking a manually wound Speedmaster replica with competitive case proportions and reliable pre-shipping performance, the N1 Factory version is a strong option to consider.
