111 Connaught Road (though see notes below).
Klaus found this 1908 entry in the Directory & Chronicle:
Sincere Co., The, Universal Providers, 111, Connaught Rd., 215 to 221, Des Voeux Road, 172, Queens Road Central & 123, Wellington Street; Tel. Ad. Sincere
At this time they still had several locations, before opening their large department store on Wing Wo Street in 1917.
The earliest mention I found in a quick Google search was from 1907, and I guess this location closed when the Wing Wo St store opened, so I've guessed the dates to be 1907-1917.
Part of this store is shown at the left edge of the photo below:
It appears to occupy three units which, according to map 1955 at https://www.hkmaps.hk/viewer.html, would place it at 110-112 Connaught Rd Central.
