{"id":8815663907066,"title":"Arnold \u0026 Son Chronometry Nebula 41.5mm Steel Skeleton Blue- 1NEAS.U01A.K002S","handle":"arnold-son-chronometry-nebula-41-5mm-steel-skeleton-blue-1neas-u01a-k002s","description":"\u003cp\u003eIn addition to being the most symmetrical of Arnold \u0026amp; Son’s watches, it is ultra-thin, at just 8.73 mm. Available with a steel bracelet or a blue rubber strap, the Nebula 41.5 Steel radiates cool and intense elegance.\u003c\/p\u003e\n\u003cp\u003eThe first generation of the Nebula established its place in the House’s galaxy. Drawing on the legacy of John Arnold, a new star emerges to join this collection. The Nebula 41.5 Steel introduces different color treatments, new finishes, and new, even more powerful and attractive details.\u003c\/p\u003e\n\u003cp\u003eThe name Nebula was chosen as a reference to the giant cloud of dust and gas in space. Some nebulas emerge from the gas and dust expelled when a dying star, like a supernova, explodes. Other nebulas are regions where new stars start to form. The seven bridges on the dial side of this timepiece radiate from the centre outwards, giving this sculptural movement the impression of a cosmic explosion.\u003c\/p\u003e\n\u003cp\u003eThe A\u0026amp;S5201 calibre was specially created for this piece and brings all of its character. It is set apart by its skeletonisation and almost perfect symmetry. The traditional shape of its bridges harks back to John Arnold’s chronometers and their openworked structure accentuates the feeling of lightness in a very mechanistic design.\u003c\/p\u003e\n\u003csection class=\"wp-block-wt-media-text alignfull has-large-media-width has-media-on-the-right\"\u003e\n\u003cdiv class=\"wp-block-wt-media-text__container\"\u003e\n\u003cdiv class=\"wp-block-wt-media-text__content has-prose-max-w\"\u003e\n\u003cdiv class=\"wp-block-wt-prose\"\u003e\n\u003cp\u003eThe A\u0026amp;S5201 calibre was conceived as a skeleton mechanism instead of being modified by removing material. The result is a completely clear and legible display on both sides. One by one, the components reveal their subtle finishes, adopting strict, fluid forms. The sum of these details and the overall approach make this calibre a special case in the exclusive circle of skeleton movements. For instance, it presents a total power reserve of 90 hours, only requiring it to be hand-wound every three-and-a-half days. At 4 mm thick, the calibre contributes to the piece’s overall slimness. The Nebula 41.5 Steel measures 8.73 mm thick, making it a natural member of the ultra-thin category.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"wp-block-wt-media-text alignfull has-medium-media-width

The Nebula 41.5 Steel measures 8.73 mm thick, making it a natural member of the ultra-thin category.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"wp-block-wt-media-text alignfull has-medium-media-width has-media-on-the-right has-horizontal-padding-on-mobile has-white-color has-chronometry-gradient-background has-text-color has-background has-link-color wp-elements-9b25e8bcadd26c0594e3978bf1b8db0b\"\u003e\n\u003cdiv class=\"wp-block-wt-media-text__container\"\u003e\n\u003cfigure class=\"wp-block-wt-media-text__media\"\u003e\u003cpicture\u003e\u003csource media=\"(min-width: 1536px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=1028 1028w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 1536px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=605 605w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 1280px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=808 808w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 1280px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=404 404w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 1024px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=648 648w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 1024px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=324 324w\" sizes=\"30vw\"\u003e\u003csource media=\"(min-width: 768px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=612 612w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=824 824w\" sizes=\"50vw\"\u003e\u003csource media=\"(min-width: 768px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=306 306w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=412 412w\" sizes=\"50vw\"\u003e\u003csource media=\"(min-width: 640px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=1028 1028w\" sizes=\"100vw\"\u003e\u003csource media=\"(min-width: 640px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=640 640w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=768 768w\" sizes=\"100vw\"\u003e\u003csource media=\"(min-width: 0px) and (-webkit-min-device-pixel-ratio: 1.5)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=720 720w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=750 750w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?quality=80\u0026amp;width=828 828w\" sizes=\"100vw\"\u003e\u003csource media=\"(min-width: 0px)\" srcset=\"https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=360 360w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=375 375w, https:\/\/cdn.arnoldandson.com\/content\/uploads\/2024\/03\/08061428\/1NEASU01AK002S-Nebula-415-Steel-caseback.png?width=414 414w\" sizes=\"100vw\"\u003e\u003c\/source\u003e\u003c\/source\u003e\u003c\/source\u003e\u003c\/source\u003e\u003c\/source\u003e\u003c\/source\u003e\u003c\/picture\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e"}
Product Description
In addition to being the most symmetrical of Arnold & Son’s watches, it is ultra-thin, at just 8.73 mm. Available with a steel bracelet or a blue rubber strap, the Nebula 41.5 Steel radiates cool and intense elegance.
The first generation of the Nebula established its place in the House’s galaxy. Drawing on the legacy of John Arnold, a new star emerges to join this collection. The Nebula 41.5 Steel introduces different color treatments, new finishes, and new, even more powerful and attractive details.
The name Nebula was chosen as a reference to the giant cloud of dust and gas in space. Some nebulas emerge from the gas and dust expelled when a dying star, like a supernova, explodes. Other nebulas are regions where new stars start to form. The seven bridges on the dial side of this timepiece radiate from the centre outwards, giving this sculptural movement the impression of a cosmic explosion.
The A&S5201 calibre was specially created for this piece and brings all of its character. It is set apart by its skeletonisation and almost perfect symmetry. The traditional shape of its bridges harks back to John Arnold’s chronometers and their openworked structure accentuates the feeling of lightness in a very mechanistic design.
The A&S5201 calibre was conceived as a skeleton mechanism instead of being modified by removing material. The result is a completely clear and legible display on both sides. One by one, the components reveal their subtle finishes, adopting strict, fluid forms. The sum of these details and the overall approach make this calibre a special case in the exclusive circle of skeleton movements. For instance, it presents a total power reserve of 90 hours, only requiring it to be hand-wound every three-and-a-half days. At 4 mm thick, the calibre contributes to the piece’s overall slimness. The Nebula 41.5 Steel measures 8.73 mm thick, making it a natural member of the ultra-thin category.
