Tsar Bomba Chivalry 8213 Modular Automatic Watch – Interchangeable Bezel, Crown, Strap

The Tsar Bomba Chivalry 8213 is a modular automatic watch built around an interchangeable component system — bezel, crown, and strap can all be swapped to personalize the watch’s look. Oval stainless steel case with sapphire crystal. FKM rubber strap with buckle clasp. 44mm dial diameter, 13mm thick, 5Bar (50m) water resistance. Available in multiple colour combinations.

Key Specifications

Interchangeable Modular System

The defining feature of the Chivalry 8213 is its component-swap design — the bezel, crown, and strap can each be exchanged independently, allowing the watch to be reconfigured into different colour combinations and visual styles without needing a separate watch for each look. The system is designed for quick, tool-minimal assembly, so components can be swapped as often as the wearer likes. This is a genuinely different proposition from a fixed-configuration watch: rather than choosing one colourway at purchase, the Chivalry 8213 is built around ongoing customization.

Oval Stainless Steel Case

At 44mm dial diameter and 13mm thick, the Chivalry 8213 has a substantial, eye-catching presence, set in an oval case shape distinct from the round or tonneau cases found elsewhere in the Tsar Bomba range. The stainless steel construction provides the structural durability needed to support repeated bezel and crown swapping without degrading the fit over time.

Sapphire Crystal

Genuine sapphire crystal — Mohs 9 hardness, providing strong scratch resistance for a watch likely to see frequent handling during component changes.

Movement

The Chivalry 8213 uses an automatic self-winding movement. The supplier’s available documentation does not name a specific caliber for this model — unlike some other Tsar Bomba models in the range, which specify named Citizen, Miyota, or Epson calibers. As with any automatic watch, it self-winds through wrist motion; confirm directly with Tsar Bomba or the seller if precise movement documentation (jewel count, power reserve, accuracy) is important to your purchase decision.

FKM Rubber Strap

The strap uses FKM (fluororubber) — a durable synthetic material resistant to chemicals, sweat, heat, and UV exposure, well suited to daily wear and the interchangeable strap-swapping system this watch is built around.

Luminous Hands

The hands carry luminous coating for improved low-light and nighttime readability.

5Bar Water Resistance

Rated 5Bar (50 meters) — suitable for daily wear, handwashing, rain, splashes, and swimming. Not intended for diving or high-pressure water exposure. Component-swapping (bezel, crown) should be done when the watch is dry to maintain seal integrity at each interface point.

How Modular Customization Works

Quick, tool-minimal assembly is the core design principle — components are designed to be swapped anywhere, without needing a dedicated workshop setup. This makes the Chivalry 8213 well suited to buyers who want one watch that adapts to different outfits or moods, rather than maintaining multiple complete watches for the same purpose.

How It Compares

The Chivalry 8213 is the modular, component-swap entry in the Tsar Bomba range — distinct from the fixed-configuration Tsar Bomba TB8216 Neutron (titanium, power reserve indicator), the Tsar Bomba TB8208 and TB8208CF (carbon fiber automatics), and the Tsar Bomba TB8211 (quartz chronograph). If component customization is the priority, the Chivalry 8213 is the only model in the range built around that proposition.
