Seen a review about ETA2892 movement, it could possibly run up to approx. 46-48 provided the components are in tiptop condition. Else, 40-42+/- is consider normal duration.

Mine is newly purchased.. I believe that since 2014 production they had switched ETA2892 with SW300 as base movement for their BR03-92 series..

I have the same watch.  In technical notes from official BR website said:

BR 03-92
Movement: mechanical with automatic winding. Calibre BR-CAL.302. 37 jewels. 28,800 vibrations per hour. Power reserve approximately 40 hours. High precision setting to 4 positions (tolerance of 0/+10 seconds per day). Func- tions: hours, minutes and seconds. Date with quickset. Time-setting with hack- ing function. Case: 42 mm in diameter.

At first I thought this watch use ETA2892(21 jewels)  or Sellita SW300 (26 jewels)  but this movement has a 37 jewels. Correct me if I overlooked something.

Anything is possible... i had a Panerai "10 days"... thats 240 hours of reserve.... if i wore it a couple of times a month then it would never stop.... was great
