The AVI-8 Bethlem is the Spitfire Lock Chronograph, model AV-4089-0B, identified by the brand as an Imperial War Museums Edition.

The specifications and buying terms below are manufacturer-published; they are not independent measurements or hands-on test results.
What is the AVI-8 Bethlem Spitfire Lock Chronograph?
Bethlem is a specific model in AVI-8’s Spitfire Lock Chronograph line. Its reference is AV-4089-0B. AVI-8 describes it as an Imperial War Museums Edition and frames the edition as a partnership inspired by aircraft and wartime aviators, connected to IWM’s collecting and preservation mission. That describes the brand’s account of the collaboration; the cited product information does not establish fundraising, a limited production run, or an endorsement beyond the stated partnership. AVI-8’s Bethlem product page and its Imperial War Museums Edition collection provide the brand’s description.

AVI-8’s figures are useful for comparing the watch on paper, but case dimensions alone cannot establish how it will fit a particular wrist. The product page specifies a mineral lens, not sapphire. Its 5 ATM rating is not, by itself, a specific swimming or diving recommendation; consult the manufacturer’s guidance for the intended use.

How big is the AVI-8 Bethlem?
AVI-8 lists a 42.0 mm case diameter, 12.0 mm thickness and 50.0 mm lug-to-lug length. The lug-to-lug figure is relevant when considering how broadly the case may span the wrist, while thickness affects how far it may sit above it. These numbers do not guarantee fit or comfort; wrist shape, strap adjustment and personal preference matter.
What does “Imperial War Museums Edition” mean?
AVI-8 presents the Bethlem as part of its collaboration with Imperial War Museums and describes the collection as drawing on aircraft and wartime aviators. The edition label identifies that collaboration context; the available product details do not specify that a purchase supports the museum financially, that production is limited, or that IWM makes claims about the watch’s performance. The collection page also includes watches inspired by other aircraft, including a Hawker Hurricane dual-time model and a P-51 Mustang chronograph; those are separate products rather than direct Bethlem equivalents.

What should you check before buying?
Price and availability depend on region
AVI-8’s US product page listed the Bethlem at $250 USD when checked in 2026. Its live regional pages can show different prices, and stock can change; do not treat the US figure as a worldwide or guaranteed current price. Confirm the price and availability on the page for your country. The brand’s US product page, IWM edition collection and Spitfire Lock collection are the relevant places to check.
Shipping, returns and warranty are policy details, not watch specs
On the US page, AVI-8 states free shipping, shipment within three business days unless otherwise indicated, and returns within 30 days after delivery. It describes a 24-month international warranty beginning at purchase and requiring registration. These terms may differ by region or change, so read the current local checkout and warranty terms before ordering.
