Refined to Endure.\u003c\/strong\u003e Certamen is the sport-elegant expression for women — a 24mm or 36mm watch that balances active materials with a calm design language. It is built for movement, finished with restraint, and shares the full modular conviction of the collection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMade to Adapt to Your Day.\u003c\/strong\u003e The modular system began with a frustration: a watch should not become unwearable because a strap broke or a style changed. Certamen brings that conviction to a women's sport context — one watch head, straps that change by hand, a case available in two sizes without compromise on Swiss quality. Time should never limit your style. Your watch should not either.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSwiss Made. Built for Movement.\u003c\/strong\u003e Each Certamen is Swiss Made, powered by a Ronda 762 movement, and finished with K1 sapphire-coated glass. The case is available in 24mm or 36mm — the 24mm with a 12mm band width, the 36mm with a 20mm band width. Two PVC sport straps are included — black and white — chosen for durability, ease of maintenance, and a clean aesthetic that moves between active and everyday. Every watch is individually numbered and produced in small batches in Switzerland, accompanied by a certificate of authenticity and a 24-month international warranty. Nine to twelve months is the timeline. Swiss made-to-order does not rush.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo Expressions. One Timepiece.\u003c\/strong\u003e Certamen is fully modular. The watch head releases from the strap without tools, and the two included PVC straps are a starting point — any compatible strap in the collection fits, 12mm straps for the 24mm case, 20mm straps for the 36mm case, whether PVC, leather, or metal link. A morning run and an evening out no longer require different watches. They require a different strap, changed in seconds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMake Certamen Your Own.\u003c\/strong\u003e Certamen is made to order and individually numbered — created for women who want a timepiece that moves effortlessly between an active lifestyle and everyday refinement. Two sport-inspired expressions give you the freedom to adapt the same watch to the pace of your day while keeping its distinctive character at the centre.\u003c\/p\u003e\n\u003cp\u003eChoose the expression that fits the moment.

From the moment your order is confirmed, production takes approximately 9 to 12 months.\u003c\/p\u003e\n\u003cp\u003eThat timeline is deliberate. Each watch is handmade, assembled, and quality-checked by Swiss watchmakers, then finished and individually numbered as part of a limited edition.

Venustus uses leather straps and leans toward feminine elegance. Both come in 24mm (12mm straps) or 36mm (20mm straps) and share the same modular system — the materials and character differ.\u003c\/p\u003e\n\u003ch3\u003eCan I pair Certamen with leather or metal straps?\u003c\/h3\u003e\n\u003cp\u003eYes. Any compatible strap in the collection fits — 12mm straps for the 24mm case, 20mm straps for the 36mm case — swapped by hand without tools.\u003c\/p\u003e\n\u003ch3\u003eWhat do the case sizes refer to?\u003c\/h3\u003e\n\u003cp\u003eThe numbers — 24mm, 36mm, and 42mm — refer to the watch head (the case that holds the dial and movement), not to wrist size. These are the available case sizes across the collection. A smaller case offers a more understated presence on the wrist; a larger case makes a stronger statement. Choose the case size that matches how you want the watch to look and wear. Certamen is available in 24mm and 36mm.\u003c\/p\u003e","brand":"Christopher Butendorff","offers":[{"title":"White\/Silver \/ Round \/ 24 mm","offer_id":55723450401108,"sku":"CER-SLV-RND-24","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Silver \/ Round \/ 36 mm","offer_id":55740179677524,"sku":"CER-SLV-RND-36","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Silver \/ Square \/ 24 mm","offer_id":55890646630740,"sku":"CER-SLV-SQ-24","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Silver \/ Square \/ 36 mm","offer_id":55890646663508,"sku":"CER-SLV-SQ-36","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black \/ Round \/ 24 mm","offer_id":55723450433876,"sku":"CER-BLK-RND-24","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black \/ Round \/ 36 mm","offer_id":55740179710292,"sku":"CER-BLK-RND-36","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black \/ Square \/ 24 mm","offer_id":55890646696276,"sku":"CER-BLK-SQ-24","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black \/ Square \/ 36 mm","offer_id":55890646729044,"sku":"CER-BLK-SQ-36","price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Black \/ Round \/ 24 mm","offer_id":56897271333204,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Black \/ Round \/ 36 mm","offer_id":56897271365972,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Black \/ Square \/ 24 mm","offer_id":56897271398740,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"White\/Black \/ Square \/ 36 mm","offer_id":56897271431508,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black\/Silver \/ Round \/ 24 mm","offer_id":56897271464276,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black\/Silver \/ Round \/ 36 mm","offer_id":56897271497044,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black\/Silver \/ Square \/ 24 mm","offer_id":56897271529812,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true},{"title":"Black\/Silver \/ Square \/ 36 mm","offer_id":56897271562580,"sku":null,"price":9495.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/2750\/0628\/files\/Certamen_2.png?v=1778653440","url":"https:\/\/christopherbutendorff.com\/products\/certamen","provider":"Christopher Butendorff","version":"1.0","type":"link"}
