Here is the Apple Watch Series 12 GPS 46mm listing. I used Apple India's launch release for features, and Flipkart and Smartprix for the display and spec details. You didn't give a colour or band, so the title is for the aluminium case and I've listed the SKU options for each colour.

Product Title

Apple Watch Series 12 GPS 46mm Smartwatch, Aluminium Case with Sport Band, S11 Chip, Health Sensing System

Overview

The Apple Watch Series 12 brings Apple's most powerful wearable chip, the S11, together with an all new Health Sensing System. New optical and electrical heart sensors track heart rate every five seconds and measure heart rate variability far more often than before, powering daily Readiness scores and overnight vitals. The 46mm Retina OLED display is protected by Ceramic Shield 2 on the aluminium case, which Apple says is 60% tougher than the glass on Series 11. A redesigned pedometer delivers more accurate step tracking, and fast charging adds up to 12 hours of use in just 15 minutes. With ECG, sleep apnea notifications, Cycle Tracking and 50 metre water resistance, it suits everyday wear, workouts and sleep.
