Vacheron Constantin Super Clone Watches 1:1 Overseas Perpetual Calendar Ultra-Thin Steel Dial

Original price was: $1,250.00.Current price is: $990.00.

TWF Edition — Integrated Steel Bracelet

TW Factory (TWF) presents a compelling iteration of the Vacheron Constantin Overseas Perpetual Calendar, balancing complex dial architecture with a verified 11.6mm case profile. This release addresses previous market limitations by refining the module integration, allowing all sub-dial complications to function reliably while maintaining the distinctive Maltese cross bezel geometry.

Powered by a robust Asian 2836-2 base movement heavily modified to replicate the visual architecture of the Caliber 1120 QP/1. The movement features a customized compass rose rotor and decorative plates, delivering a stable beat rate and approximately 36 hours of power reserve. The modular approach ensures the day, date, and month indications operate smoothly.

Crafted from 316L stainless steel with a 904L steel integrated bracelet, the 41.25mm case weighs exactly 164.4g, offering substantial wrist presence. The crisp white dial—often paired by collectors with a deep green aftermarket rubber strap for contrast—displays the calendar functions with sharp typographical precision.

  • Movement: Asian 2836-2 Base (Cal. 1120 QP/1 Decoration) — Approximately 36 hours
  • Case Material: 316L Stainless Steel, 41.25mm diameter, 164.4g total weight
  • Bezel: Polished steel Maltese cross design, accurate alternating finish
  • Crystal: Scratch-proof Sapphire with colorless anti-reflective coating
  • Bracelet: 904L Stainless Steel integrated bracelet with dual-deployant clasp
  • Water Resistance: 30m stated rating — professional pressure test recommended before swimming

Designed for the horological enthusiast seeking high-complication aesthetics without the fragility of genuine ultra-thin perpetual modules. The 11.6mm thickness allows it to slip under a cuff while offering robust daily wearability.

Description

TWF Vacheron Constantin Overseas Perpetual Calendar 4300V

A technically ambitious replica that achieves functional calendar displays and a verified 11.6mm thickness, setting a solid standard for modular clone complications.

Powered by A2836 Modular Caliber

The underlying mechanism utilizes a robust Asian 2836-2 base, fitted with a custom calendar module to support the quad-subdial layout. While it lacks the true free-sprung Gyromax-style balance of the genuine, the modular approach ensures reliable day, date, month, and 24-hour day/night indications. The custom rotor is skeletonized to mimic the 22K gold compass rose design of the authentic Caliber 1120 QP/1, visible through the sapphire caseback.

⏱ Accuracy Profile:

Standard ETA/clone base movements: ±10–15 s/day. This modular A2836 is regulated prior to assembly to ensure stable amplitude despite the added torque requirements of the calendar module.

  • ✅ Power Reserve: Approximately 36 hours
  • ✅ Complications: Day at 9 o’clock, Month at 12 o’clock, Date at 3 o’clock, Day/Night at 6 o’clock
  • ✅ Winding Direction: Bidirectional automatic winding

Technical Specifications

THE BUILD316L Stainless Steel

The tonneau case measures 41.25mm in diameter with a verified thickness of 11.6mm. The alternating brushed and polished surfaces highlight the complex geometry of the Overseas lineage.

THE DIALCrisp White Layout

The dial layout accurately positions the four registers. Printing sharpness is commendable, and the applied indices are filled with adequate luminous compound for low-light legibility.

THE BEZELSteel Maltese Cross

The signature six-sided bezel features high-polish facets against a brushed base. The transition lines are crisp, though macro inspection reveals slightly softer inner angles compared to the authentic piece.

THE BRACELET904L Steel Integrated

Constructed from upgraded 904L steel, the bracelet features the iconic half-Maltese cross links. The hidden deployant clasp engages securely with acceptable endplay tolerances.

Why TWF for This Reference?

Many collectors ask: “Why not standard factory releases?”

TWF specifically focused on reducing case thickness for this high-complication model. While older iterations hovered around 13–14mm due to the bulky module stack, TWF’s verified 11.6mm profile completely transforms the wrist dynamic, making it wear much closer to its “Ultra-Thin” namesake.

Full Disclosure: The 6 o’clock sub-dial operates as a 24-hour day/night indicator rather than a true 29.5-day moonphase, a necessary compromise when utilizing the A2836 modular base.

Collector Q&A

Q: Does the perpetual calendar function automatically adjust for leap years?

A: No. Because this replica utilizes an A2836 base with a custom calendar module, it functions as an annual or complete calendar rather than a true mechanical perpetual calendar. The month and day must be manually advanced at the end of shorter months.

Q: Is the 6 o’clock register a true moonphase?

A: On the TWF edition, the 6 o’clock register functions as a 24-hour day/night indicator (monophase) rather than a true 29.5-day astronomical moonphase. This is a common technical limitation of the A2836 modified movement.

Q: How accurate is the 11.6mm case thickness compared to genuine?

A: The genuine Vacheron Constantin Overseas Ultra-Thin Perpetual Calendar measures 8.1mm thick. While TWF’s 11.6mm is an impressive engineering feat for a modular replica movement and wears exceptionally well, it is noticeably thicker than the authentic ultra-thin profile.

Q: What is the most notable flaw on the TWF Overseas Perpetual Calendar?

A: Beyond the functional differences in the calendar module and moonphase, the bracelet clasp tolerances on the TWF possess slightly more lateral play than the genuine article. Additionally, the movement decoration, while visually mimicking the Cal. 1120 QP/1, lacks the deep, refined anglage seen under a loupe on the authentic caliber.
