The Brellum Pilot GMT LE.3 Chronometer, reference DB.CH.930, is a green-dial automatic chronograph with a 24-hour GMT hand. Launched in 2023 as a 27-piece worldwide limited edition, it pairs Brellum’s COSC-certified BR-754 movement with a 41.8 mm steel case, box-shaped sapphire crystals and 100 m water resistance. The prices reported at launch were CHF 3,150 and US$3,500; neither establishes today’s price or availability.
What is the Brellum Pilot GMT LE.3?
DB.CH.930 is the green-dial version of Brellum’s Pilot GMT LE.3 Chronometer, introduced in November 2023. Fratello reported a run of 27 individually numbered watches; Monochrome reported numbering from 01/27 through 27/27. The limited run is a defining part of the model, not a statement about whether one can still be bought.
The LE.3 combines a pilot-style Arabic-numeral dial, a second-time-zone display and a 12-hour chronograph. Its mechanical movement is Brellum calibre BR-754, based on Valjoux 7754 architecture and described by watch publications as COSC-certified.
How the dial and functions work
The green opaline dial has luminous Arabic numerals and markers, three subdials, and red accents on the GMT text and hand tips. The date appears in the 6 o’clock register. The three registers accommodate the date, running seconds and chronograph counters, including a 30-minute counter and 12-hour totalizer.

A dedicated hand indicates the second time zone against a 24-hour scale. Launch coverage describes it as independently adjustable through the crown’s second position. The chronograph measures elapsed time, while the running-seconds register continues to show the movement is operating.
Case, dimensions and wear
The case is 316L stainless steel, with sapphire crystals on both the front and back. Fratello reports 41.8 mm diameter, 51.8 mm lug-to-lug and 15.9 mm overall thickness, including the box-shaped crystals; the steel case itself is reported as 11.7 mm thick. The published water-resistance rating is 100 m.

The proportions deserve a close look before buying. Fratello’s reviewer considered the watch better suited to medium or larger wrists and noted that the bracelet’s intermediate links increase its effective span beyond the nominal lug-to-lug measurement. That is one reviewer’s fit assessment, not a universal wrist-size rule. If possible, compare the bracelet’s end-link reach as well as diameter, lug-to-lug and overall thickness.
The launch coverage says the watch was supplied with both a five-row steel bracelet and a brown nubuck/leather strap. That gives the original package two wearing options; present-day availability of the full set is not established.

Current stock and pricing for DB.CH.930 are unverified. Brellum’s current homepage describes its direct-to-client approach and shows current shop categories, but does not establish that this reference remains available. Contact Brellum or a reputable seller to check availability, condition, included accessories and the price in your market; the limited-edition run alone does not prove the watch is discontinued or unavailable on the secondary market.
What to compare before choosing it
When comparing this watch with another GMT chronograph, the headline diameter is only part of the fit question. Consider the full 51.8 mm lug-to-lug measurement, 15.9 mm overall thickness and how the bracelet extends beyond the case. For function and value, compare the GMT adjustment method, chronograph layout, water resistance, certification, power reserve, included wear options, edition size and the price actually offered in your region.
