AB0134101l2A1","description":"\u003cpre style=\"font-family:inherit;\"\u003eCASE #575 — BREITLING CHRONOMAT 42 REF. AB0134101L2A1\nStatus: Active Investigation\nCondition: Very Good Pre-Owned\nScope: Box and Papers (Jomashop Card — No Original Warranty Card)\nYear: Unknown\n\n🔎 CASE NOTES\n\nThe Chronomat is, without equivocation, the backbone of the Breitling empire — the model that pulled the brand from the edge of obscurity in 1984 and reasserted its dominance in the world of mechanical chronographs. Reference AB0134101L2A1 represents the modern evolution of that lineage: a 42mm steel case fitted with the rich, deeply saturated green stick dial that has become one of the most sought-after colorways across the contemporary luxury landscape. This is not a watch that follows trends — it set them, and then had the decency to outlast them.\n\nThe Chronomat 42 occupies a critical position in Breitling's current catalog. It sheds the sometimes-polarizing bulk of earlier Chronomat generations while retaining the unmistakable rider-tab bezel, the muscular case architecture, and the serious horological credibility of an in-house COSC-certified caliber. The green dial variant, in particular, has proven itself a quiet assassin on the secondary market — drawing collectors who want presence without cliché, and color without compromise.\n\nThis specific example arrived at BST in very good condition, presenting well on the wrist with only the telltale signs of a watch that has been worn — not abused. The absence of an original Breitling warranty card, replaced here by a Jomashop card, is a material detail that demands full transparency in the case file and will be addressed accordingly below.\n\n🕰️ THE EVIDENCE\n\nReference: AB0134101L2A1\nModel: Chronomat 42\nCase: Stainless Steel\nCase Size: 42mm\nBezel: Stainless Steel Rider-Tab Bezel\nCrystal: Sapphire (Anti-Reflective Coated)\nDial: Green Stick\nMovement: Breitling Caliber 01 — Automatic (COSC-Certified Chronometer)\nBracelet: Stainless Steel President-Style Bracelet\nYear: Unknown\nAccessories: Box, Papers (Jomashop Card — No Original Breitling Warranty Card)\n\nCondition Notes: Watch presents in very nice overall shape. Minor wear is visible on the high-polished surfaces of the bezel — consistent with regular, careful wear. Some additional wear noted along the sides of the case. Bracelet and clasp are in strong condition. Crystal is clean. Chronograph function and timekeeping are performing as expected from a COSC-certified movement.\n\n⚙️ THE MOVEMENT — CALIBER 01\n\nBeneath the caseback lies Breitling's crown jewel: the in-house Caliber 01. This is no borrowed architecture or outsourced convenience. The B01 is a column-wheel, vertically-coupled chronograph movement developed and manufactured entirely within Breitling's own facilities. It delivers a 70-hour power reserve, a 28,800 vph frequency, and carries the COSC chronometer certification that Breitling has staked its reputation on for decades. In a market saturated with ETA-powered pretenders, the B01 is a genuine statement of mechanical intent. It is the reason serious collectors take the modern Chronomat seriously.\n\n📋 THE WARRANTY CARD QUESTION\n\nThis is a detail BST does not gloss over. The original Breitling warranty card is not present with this example. In its place is a Jomashop card — indicating the watch was originally purchased through the grey market. For collectors, this distinction matters: grey market purchases are fully authentic but fall outside the brand's authorized dealer network, meaning Breitling's factory warranty would not have applied. On the secondary market, the absence of an original warranty card typically affects resale value by a modest but measurable margin. The watch itself is no less genuine, no less mechanically brilliant — but the paper trail tells a different story than a boutique purchase, and this file reflects that honestly.\n\n🌟 COLLECTOR PROVENANCE\n\nGreen dials have moved from novelty to mainstay in the collector world, but few execute the colorway with the depth and authority of this Chronomat reference. The sunburst green, paired with polished stick indices and the bold architecture of the rider-tab bezel, creates a watch that commands attention without descending into flamboyance. On the president-style bracelet — with its blend of polished and brushed links — the watch sits with a heft and refinement that belies its tool-watch DNA.\n\nFor the collector hunting a modern Breitling powered by genuine in-house caliber, presented in a compelling dial variant, and priced below what a full-kit boutique example would command, this is a case worth examining closely. The Jomashop card will narrow the audience slightly — but for the buyer who prioritizes the watch over the provenance paper, it also narrows the price.\n\n🧾 FROM THE CASE FILE\n\nBreitling Chronomat 42, reference AB0134101L2A1. Stainless steel, 42mm, green stick dial, in-house Caliber 01 automatic chronograph, COSC-certified. Presented on stainless steel president bracelet. Very good condition with minor wear to bezel high-polish surfaces and case sides. Complete with box and Jomashop card. No original Breitling warranty card. Year of production unconfirmed.\n\n🗝️ BST VERDICT\n\nThis is a serious chronograph powered by one of the finest in-house movements in its price class, wearing one of the most compelling dial colors in the current market. The grey market provenance and absent warranty card are reflected fairly in the asking price — making this a strong entry point into the modern Chronomat line for the collector who buys the watch, not the paperwork.\n\n👉 Every case deserves a closer look.\u003c\/pre\u003e","brand":"Baker Street Timepieces","offers":[{"title":"Default Title","offer_id":58288188653871,"sku":null,"price":5500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/5359\/5439\/files\/1D0FD26E-F4B1-4ACE-A1AF-3D55731C62FA.jpg?v=1785891747","url":"https:\/\/bakerstreettimepieces.com\/products\/case-575-breitling-chronomat-42-ref-ab0134101l2a1","provider":"Baker Street Timepieces","version":"1.0","type":"link"}
