The Tudor 79540 movement, while not a movement name typically associated with the spotlight, is the unsung hero powering a particularly appealing and versatile iteration of the Tudor Black Bay collection: the Heritage Black Bay 41 ref. 79540. This article delves into the significance of the 79540, its role within the Black Bay 41, and its place in the broader Tudor landscape. We'll explore the specifications, the overall design philosophy of the Heritage 79540, and what makes the Tudor Black Bay 41 such a compelling choice for watch enthusiasts.

Tudor Heritage 79540: A Foundation of Reliabilitytudor 79540 movement

The Tudor Heritage Black Bay 41 (ref. 79540) is a watch that emphasizes everyday wearability and a classic aesthetic. It achieves this largely thanks to the reliable and robust automatic movement beating within its heart: the Tudor Calibre 2824. While not an in-house movement like some of Tudor's other offerings, the ETA 2824 (or its Sellita SW200 equivalent, depending on the specific production year) forms the backbone of the 79540's functionality.

It's crucial to understand that the "79540" designation refers to the *model* of the watch, not explicitly the movement itself. The *movement* is the workhorse, the engine; the *model* is the entire vehicle. The Tudor Heritage Black Bay 41 (79540) utilizes a well-proven, readily serviceable movement (ETA 2824 or Sellita SW200) known for its accuracy and dependability. This strategic choice allows Tudor to offer a high-quality timepiece at a more accessible price point.

Tudor 79540 Specs: The Calibre 2824/SW200 Under the Hood

Let's break down the essential specifications of the movement that powers the Tudor Heritage Black Bay 41 (79540):

* Type: Automatic, self-winding mechanical movement.

* Base Calibre: ETA 2824-2 or Sellita SW200-1 (likely used interchangeably by Tudor depending on supply).

* Diameter: Typically around 25.6mm (11.5 ligne).

* Height: Approximately 4.6mm.

* Jewels: Usually 25 jewels in the ETA 2824-2 and 26 jewels in the Sellita SW200-1. These jewels minimize friction at crucial moving parts, enhancing longevity and accuracy.

* Frequency: 28,800 vibrations per hour (4 Hz). This higher frequency contributes to a smoother sweep of the seconds hand and potentially improved accuracy.

* Power Reserve: Around 38 hours. This is the amount of time the watch will continue to run after being fully wound, even if not worn.

* Functions: Hours, minutes, central seconds hand, and date (on some variations of the Black Bay 41).

* Hacking Seconds: Yes. This feature allows the seconds hand to stop when the crown is pulled out, enabling precise time setting.

* Quickset Date: Yes. The date can be advanced independently of the time using a specific crown position.

* Regulation: Tudor regulates these movements to ensure they meet their standards for accuracy. While not COSC certified (unlike movements in some other Tudor models), they are generally reliable and accurate.

The Tudor Heritage Black Bay 41 (79540): Striking a Balance

The Heritage Black Bay 41 ref. 79540 is a testament to the principle of "less is more." It takes the design cues of the iconic Black Bay series but scales them down to a more universally appealing 41mm case size. This makes it a versatile watch suitable for a wider range of wrist sizes and occasions.

Here's what makes the Black Bay 41 (79540) stand out:

* Case Size: The 41mm stainless steel case is the sweet spot for many. It offers presence without being overwhelming. The thickness is also relatively slim, making it comfortable to wear under a cuff.

* Dial: The dial is clean and legible, featuring applied hour markers and the signature "snowflake" hands, a hallmark of Tudor's diving watches. The absence of a rotating bezel, unlike other Black Bay models, gives the 41 a dressier, more refined appearance.

* Crystal: A domed sapphire crystal protects the dial, offering excellent scratch resistance and a vintage-inspired aesthetic.

* Bracelet/Strap Options: The Black Bay 41 (79540) is typically available with a stainless steel bracelet, a leather strap, or a fabric strap. The bracelet offers a robust and classic look, while the leather and fabric options provide a more casual and comfortable feel.

* Water Resistance: 150 meters (500 feet). This makes it suitable for swimming and snorkeling, but not for deep-sea diving.

* Design Simplicity: The overall design is intentionally understated. The polished and brushed surfaces of the case, the clean dial layout, and the absence of unnecessary embellishments contribute to its timeless appeal.
