Stella Sora Original Watch Demon Lord Model
This original solar watch works motifs associated with the Demon Lord into its design throughout.
While reflecting the game's world in its details, it keeps a simple, easy-to-wear design that blends naturally into everyday outfits.
The watch uses a Japanese-made solar movement (SEIKO EPSON VS37) that turns light into power. Unlike a typical battery-powered watch, it does not need regular battery replacement, which makes it convenient for everyday use.
The hour hand is designed after the "Seal of Blessing" (恩恵の印章) of the Demon Lord, who governs "tense" (時制), while the minute hand takes its motif from the "Demon Lord's Key" (魔王の鍵).
The mark symbolizing the Demon Lord's authority is laid out in three dimensions. The mark also appears on the buckle of the stainless steel bracelet, so the Demon Lord can be felt down to the smallest detail.
The watch has enhanced daily-life water resistance (10 ATM), so it can be used with confidence in daily life.
Note: The case back uses a screw-back structure to improve water resistance. For manufacturing reasons, the orientation of the case back and the position of the lettering may differ from the photos.
The 40 mm case has a balanced size, with enough presence while still fitting easily under a sleeve cuff. Leaving out the calendar display keeps the dial clean, resulting in a simple design with excellent legibility.
The interior of the dedicated box is designed with the Demon Lord in mind. The outside features foil stamping inspired by the "Star Tower" (星ノ塔), so the packaging also expresses the game's world.
Purchase Bonus
Each purchase comes with a microfiber cloth printed with an illustration drawn exclusively for it by illustrator 春夏冬ゆう (https://x.com/akinashi_yu). Besides the watch, the cloth can be used to clean smartphones, glasses, and more.
Warranty Card
The warranty card is an original design on a PVC card, inspired by the Demon Lord's "mobile phone" (ケータイ).

Estimated delivery dates differ depending on when the order is placed. Shipping may also be earlier or later depending on the number of orders.
- The watch is made to order, so orders are accepted only during the order period.
- Because production begins after an order is received, shipping takes some time.
- If many orders are received, items ship in the order of the orders placed, so delivery dates will vary.
