• intros：{"brand_intro":"B&R源自瑞士比尔，由前劳力士制表师Hans Rüeger于1998年创立。品牌最初为高端表店定制展示柜，后转型为腕表周边配件专家。B&R的核心技术在于'多层磁路分流'设计，通过交替排列的μ金属和铜箔层，在极薄壁厚下实现高屏蔽效能。其产品被百达翡丽、朗格等品牌官方售后推荐使用。B&R坚持瑞士手工组装，每只表盒附带独立编号和屏蔽性能证书，品控标准参照ISO 14644-1 Class 7洁净室等级。","product_intro":"BR-700C是B&R的轻量化旗舰，采用航空级碳纤维外壳搭配内部μ金属屏蔽层，整体重量仅1.2kg，适合旅行携带。产品可容纳2只大表径腕表（最大50mm），内部隔板可拆卸。核心卖点是'极速消磁'——内置被动消磁回路，可在48小时内将已受磁腕表恢复至出厂精度。相比万宝的堆料路线，B&R更强调设计美学与便携性，但价格是前者的5倍。适合经常出差、需要随身携带贵重腕表的商务人士。","key_specs":{"屏蔽材料":"μ金属+铜箔复合层，厚度2.5mm","内部尺寸":"200×120×80mm（2只装）","屏蔽效能":"≥35dB（99.97%衰减）","外壳材质":"3K碳纤维编织+铝合金骨架","重量":"1.2kg","适用人群":"高端腕表拥有者、频繁差旅人士、腕表收藏入门者"}}
