Happen to see another SBBN 021 in a shop and a fellow collector friend took a snap pic of both for comparison.
Pic for comparison. After wearing this for about 3 weeks, the modded tuna has brought in response ranging from outright detest to mild and even warm liking. For sure, it polarise opinions and very much a conversational piece.
I have since swapped it to the 1000 m 7C46-0AB0 and leave the 7549-7009 back to its original state. The fit is better as the ceramic shroud is a better fit for the 7c46 Gold Tuna range.
