The Nite Icon-212 Green T100 Automatic is a Swiss-made automatic watch with a Sellita SW200-1 movement, a 44 mm case and tritium illumination. Its available handbook listing gives useful operating and specification details, but current price, stock and independent performance results are not established here. This is a specifications-and-operation review, not a hands-on verdict.
What the Icon-212 Green T100 Automatic is
The model-specific details below are listed in the Icon Automatic Series handbook as reproduced by Juhend.ee. NITE’s official handbook index confirms that the company publishes an Icon Automatic handbook, but the model-specific PDF was not directly inspected for this review.
| Specification | Handbook listing |
|---|---|
| Movement | Swiss-made Sellita SW200-1 automatic |
| Case material | 316 stainless steel |
| Crystal | Sapphire with triple anti-reflective coating |
| Case diameter | 44 mm |
| Dial diameter | 38 mm |
| Case depth | 14.1 mm |
| Lug width | 22 mm |
| Water resistance | 100 m |
| Strap options | Leather or stainless-steel bracelet |
| Listed weight | 95 g on leather; 195 g on bracelet |
| Spring bars | Two 22 mm spring bars |
These are handbook-listed figures rather than independent measurements. A 44 mm case and 14.1 mm depth are the key sizing numbers for a prospective wearer; the listing also gives the smaller 38 mm dial dimension, which should not be confused with case diameter.
What T100 means on this watch
NITE Watches explains that “The T rating relates to the total watch radiation content measured in millicuries.” The company defines T25 models as containing up to 25 mCi and T100 models as containing above 25 mCi and up to 100 mCi. The figures describe total tritium content, not a measured brightness comparison between this watch and a T25 model.

NITE describes its tritium illumination as self-powered and continuously glowing, and says illumination can last up to 20 years. Those are manufacturer-wide claims; they are not an independently verified lifetime or brightness measurement for this exact Icon-212. NITE presents the choice between T25 and T100 as a matter of preference.
How to wind and set the watch
The following operation sequence comes from the handbook listing; it has not been tested on a sample for this review. The handbook identifies three crown positions after the screw-down crown is unscrewed:
Rank #2
- Steel and gold tone stainless steel case 40mm diameter x 14mm thick; Exhibition case back; Black dial; Luminous hands and hour markers
- NH35A Japanese Automatic movement, 24 jewel; Assembled in Malaysia; Watch weight: 152 grams
- Steel and gold tone stainless steel band, 205mm L x 20mm W; Band is adjustable by adding/removing links; Fold over safety clasp
- Mineral crystal; Screw-down crown; Unidirectional stainless steel bezel with black top bezel ring; 200 meter water resistant: Suitable for professional marine activity and surface water sports. Suitable for diving.
- Automatic movement means that this timeless watch powers a quality Japanese-automatic movement with the simple movement of your arm.
- Unscrew the crown counter-clockwise.
- At position 1, turn the crown clockwise to wind.
- At position 2, turn clockwise to set the desired date.
- At position 3, turn clockwise to advance the time or counter-clockwise to move it back.
How it compares on paper—and what remains unknown
The handbook listing provides the principal comparison points a buyer may want to check against other watches: movement, case and dial dimensions, T rating, water resistance, crystal and strap configuration. It does not establish a current price, stock status or exact-model seller availability. No independent accuracy, power-reserve, comparative brightness or durability results are available in the cited material, so those should not be treated as known advantages or drawbacks.
For verification, NITE’s official illumination explainer supports the company’s description of its T ratings and tritium lighting. Its official handbook index is useful for locating company manuals, while the model-specific specification listing is on Juhend.ee.
