The Brellum Wyvern Classic Petite Seconde pairs a COSC-certified automatic movement and 100 m water resistance with a dress-watch layout, small seconds and a date. Its 42.5 mm case is the key fit question: that is substantial for a dress-style watch, so compare its dimensions with a watch you already wear comfortably. Published reviews and prices date to 2018; current availability and price for this exact model are not established.

What the Wyvern Classic Petite Seconde offers

This is a steel automatic with hours, minutes, small seconds and a date at six o’clock. Its design combines a sunburst dial, applied rectangular indices and alpha hands with a box-style sapphire crystal. An exhibition caseback reveals the decorated movement.

Launch-era coverage reported black, blue and silver dial options. Strap descriptions vary by review: Watch I Love reported a handmade calf leather strap and steel deployant buckle with safety push buttons, while Worn & Wound described color-matched black, blue or tobacco-brown leather straps with a deployant buckle. These are historical descriptions, not confirmation of current configurations or accessory supply. Watch I Love, 5 December 2018; Worn & Wound, 10 December 2018.

Whodoit Uncovered Arabic Numeral Dial Mechanical Pocket Watch for Men
  • This pocket watch features a unique design with a black Arabic numeral silver dial and a lightweight back cover that does not appear bulky.
  • The packaging includes: 1 pocket watch, 1 chain, 1 operating instruction, and 1 black box.
  • Arabic numeral black case, special frame dial, and mechanical movement make it look very elegant, retro, and fashionable!
  • This pocket watch features a unique design, and the unique dial design is very versatile.
  • Mechanical movement without batteries. Automatic winding means it winds itself, and you must wind it to turn on its power. When the watch runs low due to prolonged inactivity, it also needs to be wound. By rotating the crown to wind the automatic watch until the power jump begins, the automatic winding mechanism will work.

How it may fit and wear

The 42.5 mm diameter is the most important practical consideration. Worn & Wound judged it large for a dress-style watch and potentially too large for some wrists. That is a reviewer’s assessment rather than a universal sizing rule; case shape, wrist shape and personal preference all affect fit. The reported 10.9 mm overall thickness also matters if you want a watch to slide easily beneath a close-fitting cuff.

  • Compare both diameter and thickness with a watch you already find comfortable.
  • Consider whether you want a traditional dress-watch appearance in a relatively broad case.
  • Confirm the exact dial, strap and buckle supplied with the individual watch; historical descriptions do not establish what a seller has today.

Price and availability today

The prices documented for the launch period are historical, not current offers. Watch I Love listed CHF 1,480 excluding taxes in 2018; Worn & Wound reported $1,490 in its December 2018 coverage. Neither figure should be used as a current market valuation or quote. Watch I Love; Worn & Wound.

Brellum’s current homepage describes the Wyvern collection as featuring GMT dual-time functionality, but does not establish whether the Classic Petite Seconde remains available. No current price or verified listing for this exact reference is established here. Before buying, ask the seller to confirm the reference, condition, included components and price, and check whether the watch’s service history and documentation are available. Brellum.

Warranty and servicing

Brellum’s current warranty page states a two-year warranty from purchase for manufacturing defects, subject to its terms. It requires the guarantee card and COSC certificate and says repairs during the warranty period must be carried out by a Brellum service center to preserve the international warranty. The page recommends maintenance every five years. Since these general terms do not establish coverage for a specific older or secondhand Petite Seconde, confirm eligibility with Brellum before relying on warranty protection or arranging service.

Who should consider it?

The Petite Seconde is worth considering if you want a COSC-certified automatic with a small-seconds layout, date, exhibition back and more water resistance than many dress-watch designs advertise. It is a less obvious choice if you prefer a compact dress watch or need confirmed current availability and a price before deciding. For a used example, weigh the individual watch’s condition, documentation and service history alongside the specifications; the 2018 launch prices do not tell you what a particular watch is worth now.
