如果你平常一只手錶從早戴到晚,白天要通勤、工作、接通知,晚上還要運動,甚至週末直接上山下海,耐用度與螢幕可讀性就比單純「好不好看」更重要。Apple Watch Ultra 4 採用 49 公釐 5 級鈦金屬錶殼,提供原色與黑色選擇,搭配平整藍寶石玻璃錶面,兼顧質感與戶外使用需要;隨顯 Retina 顯示器採廣視角 OLED 與 LTPO3,峰值亮度最高 3000 尼特,最低可降至 1 尼特,不論大太陽下看訓練數據、騎車途中確認資訊,或夜間查看時間,都能兼顧清楚與舒適。機身通過 MIL-STD-810H 測試,具備 WR100 防水與 IP6X 防塵,並支援最深 40 公尺的休閒水肺潛水及高速水上運動。可自訂動作按鈕也很實用,跑步時能直接開始訓練、標示區段或切換間歇,不必滿手汗還在螢幕上反覆點選。
對常忘記充電,或一到假日就安排長跑、單車、健行的人來說,手錶功能再多,撐不到行程結束都很掃興。Apple Watch Ultra 4 正常使用最長可達 50 小時,低耗電模式最長可達 84 小時;標準體能訓練跟測最長 18 小時,長時間體能訓練上限模式則最長可達 45 小時。臨時發現電量不足,也支援快速充電,充電約 15 分鐘即可提供最長 18 小時正常使用時間,早上洗澡、整理裝備的空檔就能補進不少續航。S11 晶片搭配全新健康感測系統,可更頻繁讀取心率與心率變異,並透過「準備指數」整合近期活動、生命徵象與睡眠狀況,協助判斷今天適合衝強度,還是該把訓練放輕一點。跑步時還能查看心率區間、跑步功率、步頻與配速,設定自訂訓練、配速員及路線競速,對想把「有運動」進一步變成「有計畫地訓練」的人更有幫助。
Apple Watch Ultra 4 不只適合健身房或城市慢跑,真正拉開差異的地方,是當行程走到訊號不穩、路線陌生或需要長時間待在戶外時,依然有一套可用的工具。精準雙頻 GPS 能支援跑步、騎車與健行定位;登山前可先從 iPhone 下載離線地圖並同步到手錶,途中可利用指南針航點標記營地、登山口等位置,「回溯」功能還能根據 GPS 自動整理走過的路徑,即使沒有網路,也能協助沿原路返回。喜歡水上活動的人則可搭配深度計、水溫感測器、潮汐 App,以及相容潛水 App 使用。日常安全方面,Apple Watch Ultra 4 支援跌倒偵測、車禍偵測、SOS 緊急服務與警笛;若迷路或受傷,可長按動作按鈕啟動警笛,聲音最遠可在約 180 公尺外被聽見。搭配行動網路連線時,即使不帶 iPhone 出門,也能在手腕上收發訊息、通話、聽音樂或 Podcast。對常運動、愛戶外,卻又希望平日工作與聯絡功能不用妥協的人而言,它更像是一只兼顧耐用、續航、訓練與安全的全天候腕上工具。
