N1 Factory Edition — Two-Tone Steel & Sedna Gold Bracelet

The N1 Factory (N1F) iteration of the Seamaster Diver 300M Chronograph addresses previous structural limitations by achieving an accurate 16.5mm case thickness. Weighing a substantial 227.4g on its two-tone bracelet, it provides a physical presence consistent with the genuine reference. This release establishes a strict benchmark for heavy-hitter diving chronographs on the replica market.

Powered by a heavily modified 7750-based Clone Calibre 9900, this movement correctly stacks the 12-hour and 60-minute hands within the 3 o’clock subdial. While it mimics the visual architecture of the genuine Co-Axial Master Chronometer, it operates with improved transfer gears to reduce stutter. Power delivery is rated at approximately 36 hours.

The 44mm case is constructed from 316L stainless steel, contrasted by 18K Sedna Gold plating on the bezel ring, crowns, and mid-links. The black ceramic dial features precise laser-ablated waves and raised indices filled with dual-emission Super-LumiNova.

  • Movement: Clone Calibre 9900 (7750 Base) — Approximately 36 hours
  • Case Material: 316L Stainless Steel & 18K Sedna Gold Plate, 44mm diameter, 227.4g
  • Bezel: Black ceramic with Ceragold™ tone diving scale
  • Crystal: Sapphire with dual-sided AR coating
  • Bracelet: 316L Steel and 18K Sedna Gold plated links, deployant clasp
  • Water Resistance: 30m stated — professional pressure test recommended before swimming

This piece suits collectors seeking a mechanically complex, high-mass chronograph. Its substantial 227.4g weight and 44mm profile demand a wrist capable of supporting modern oversized diver specifications.

Description

N1 Factory OMEGA Seamaster Diver 300M Chronograph 44mm (Sedna Gold)

N1F delivers a mechanically viable Co-Axial aesthetic while achieving the highly scrutinized 16.5mm profile.

Powered by Clone Calibre 9900 (7750 Base)

Replicating the in-house OMEGA 9900 is an engineering challenge due to the specific subdial layout. N1 Factory utilizes a highly modified Asian 7750 chronograph architecture, utilizing custom transfer gears to mirror the functionality of the genuine movement. The decorative plates and blackened screws are applied to simulate the Co-Axial Master Chronometer aesthetics, while the module successfully supports the stacked 12-hour and 60-minute hands at the 3 o’clock position.

⏱ Accuracy Profile:

Due to the heavy modifications on the 7750 base to support the dual-hand subdial, typical accuracy is regulated to ±10–15 s/day. Chronograph engagement is firm, characteristic of cam-actuated mechanisms.

  • ✅ Power Reserve: Approximately 36 hours
  • ✅ Complications: Stacked 12-hour/60-minute chronograph subdial, running seconds, date display
  • ✅ Winding Direction: Unidirectional (counter-clockwise rotor free-spin)

Technical Specifications

THE BUILD316L Steel & 18K Sedna Gold Plate

The 44mm case features a precise 16.5mm thickness and yields a substantial 227.4g total weight. The Sedna Gold plating is applied to the bezel ring, helium escape valve, crown, and bracelet mid-links.

THE DIALBlack Ceramic [ZrO2]

The black dial is crafted from polished ceramic, featuring deep laser-ablated waves. Super-LumiNova application on the raised indices ensures distinct blue/green emission.

THE BEZELCeramic with Ceragold™ Tone

The unidirectional rotating bezel features a black ceramic insert with diving scales rendered in a Ceragold™ tone, matching the warmth of the Sedna Gold case elements.

THE BRACELETTwo-Tone Steel & Gold

A heavy five-link bracelet construction with alternating brushed and polished finishes. The deployant clasp features micro-adjustment tolerances suitable for daily wear.

Why N1 Factory for This Reference?

Many collectors ask: “Why not OMF?”

Older OMF versions of this chronograph struggled with stuttering transfer gears and often missed the exact thickness target. N1 Factory utilizes an improved gear train to smooth the sweep and refines the case profile to exactly 16.5mm, making it structurally superior for this specific reference.

Full Disclosure: The reliance on a 7750 base means the rotor is unidirectional, resulting in noticeable freewheeling noise not present in the genuine METAS-certified caliber.

Collector Q&A

Q: Does the 3 o’clock subdial function exactly like the genuine Calibre 9900?

A: Yes, the N1 Factory utilizes a highly modified 7750 base to ensure both the 12-hour and 60-minute hands on the 3 o’clock subdial are fully functional and stacked correctly.

Q: Is the 18K Sedna Gold plating prone to fading?

A: The factory uses an advanced PVD plating process for the Sedna Gold elements. While durable for daily wear, it will eventually show wear if exposed to harsh chemicals or deep scratches, unlike solid gold.

Q: How does the weight compare to the genuine model?

A: This N1F replica weighs exactly 227.4g on the full two-tone bracelet, providing a substantial physical presence that closely mimics the heavy-hitter feel of the authentic piece.

Q: What is the main drawback of the 7750-based Clone 9900 movement?

A: Because it relies on a unidirectional winding 7750 architecture, rotor freewheeling noise is more noticeable than on the genuine Co-Axial escapement, and the power reserve is limited to approximately 36 hours.
