With both T25 and T100 GTLS illumination options available in our collection, we often get asked “what is the difference?” and “which is better?”.
The answers are relatively simple, there is a difference (keep reading) and neither is better – it’s completely subjective.
The T rating relates to the total radiation content within the watch. Radiation content is measured in millicuries (mCi), therefore, all watches with a T25 mark contain up to 25mCi and similarly, watches with a T100 mark, contain no more than 100mCi, but do exceed 25mCi.
Every single model within our collection features GTLS tubes and we only use those supplied by the marketing leading Swiss manufacturer mb-microtec; who are widely regarded as the top manufacturers of GTLS tubes with an extensive range of colour and size options.
Whilst there are differences between the total mCi content in the T25 and T100 models, the idea of “which is better” is simply a choice of personal preference and taste; much like which beer is better – ale or lager?
During the design process we decide whether to create a T25 or T100 model based on the aesthetic styling and functional design. You will note that the combinations available varies between each series.
Let us know in the comments below whether you prefer T25 or T100 and why – remember there is no right or wrong answer.
Oh, and feel free to help us decide which beer is better too!
As a brand who sells both T100 and T25 GTLS illuminated watches, we often get asked what the difference is.
Radiation content is measured in millicuries (mCi), therefore, all watches with a T25 mark contain no more than 25mCi of radiation content and similarly, watches with a T100 mark, contain no more than 100mCi.
All current Nite watches are fitted with GTLS tubes manufactured by the Swiss company mb-microtec. mb-microtec are widely regarded as the best manufacturers of GTLS tubes in the world and offer an extensive range of colour and size options. The size and colour of GTLS will ultimately determine the final mCi rating of each model.
Whilst there are differences between the amount of mCi in the T25 and T100 models, the idea of “which is better” is simply a choice of preference and taste.
It would be of interest to us to gauge from our customers, your preference, and whether this is determined by the situations you are in, activities you use the watch for, or simply down to personal taste?
Some prefer the T25 GTLS illumination due to its more understated look and design, whilst others are believers that if you are to purchase a tritium watch, then you will want as much illumination as possible, and opt for the T100 models.
Our new ICON series features both T25 and T100 models within it, below is a comparison of the T25 and T100 versions of the ICON-209S.
