Captain Osea Kolinisau acknowledged the successful history but told World Rugby it didn't play a big part in their build-up this week.
"We weren't focusing on doing it three times," Kolinisau said.
"We said that we were going to take it as if we were searching for [our] first title in the series and I am glad that everybody was up to par and everybody did their job."
Kolinisau said playing at the Hong Kong Sevens was a childhood dream for most Fijians so winning the tournament was extra special.
"Hong Kong seems like a home away from home and we watch a lot of our idols play here," he said.
"It's always the dream of every young Fijian to one day wear the white jersey but [also] wear it in Hong Kong."
