Arabic Numerals
Turns out, the digits 0 thru 9 that we commonly refer to as Arabic numerals on the dial of watch actually originated in India several centuries prior. Confounding matters, timepieces made specifically for the Arab market typically employ Mashriki, or Eastern Arabic, numerals (١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩).
